Medical Misdiagnosis Claims
When we seek medical advice, we place our trust in professionals to correctly identify what is wrong and recommend the right course of treatment. An accurate diagnosis is often the first and most important step toward recovery. When that process fails—when a serious condition is missed or wrongly identified—the consequences can be painful, distressing and, in many cases, life-changing. At PSR Solicitors, we help individuals and families across England and Wales pursue justice after being affected by medical misdiagnosis.
Our team of experienced medical negligence solicitors understands the long-term impact a misdiagnosis can have on your health, your confidence in the care system, and your daily life. Whether you received inappropriate treatment, were falsely reassured, or suffered delays in critical care, we are here to listen, advise and take action on your behalf.
We know that reaching out to a solicitor may feel overwhelming—especially when you're still dealing with the effects of what went wrong. That’s why we aim to make the process straightforward and supportive from the beginning. We will talk you through your options in plain language, handle the legal work with care, and treat your concerns with the seriousness they deserve.

I found PSR solicitors very help full and professional in their handling of my claim and would recommend the firm to any one.
They were very helpful, better value, and dealt with my claim within 7 months. After a 4 and a half years issue with my previous solicitors.
The service I received from start to finish was exceptional, everything was dealt with a timely and professional manner! I was kept informed throughout and I am extremely pleased with the outcome. I will most definitely be recommending this company to all. Well done PSR
Misdiagnosis occurs when a medical professional gives an incorrect diagnosis—mistaking one condition for another—or fails to recognise the true nature of a patient’s illness altogether. It differs from a delayed diagnosis in that the diagnosis is not just late, but wrong. This can lead to entirely inappropriate treatment, a lack of necessary intervention, or both.
In legal terms, misdiagnosis may amount to medical negligence when it can be shown that the mistake fell below the standard of care expected of a competent healthcare provider, and that the error directly caused avoidable harm. That harm may be physical—such as deterioration of an untreated condition—or psychological, such as distress from being told you had a serious illness you did not actually have.
Examples of misdiagnosis may include:
While not every diagnostic error will meet the legal threshold for a negligence claim, if you were harmed due to an avoidable misdiagnosis, you may be entitled to compensation.
At PSR Solicitors, we work with medical experts to carefully investigate what went wrong in your case, identify whether there was a breach of duty, and establish a clear link between the misdiagnosis and the harm you suffered.
Certain conditions are more prone to misdiagnosis because their symptoms can overlap with other illnesses or because healthcare professionals fail to act on red flags. Among the cases we commonly assist with are:
Early symptoms of meningitis can mimic common viral infections. A misdiagnosis can result in a critical delay in treatment, which may lead to brain damage, hearing loss or death—especially in children and young adults.
Appendicitis is often misdiagnosed as a stomach bug or urinary infection. If left untreated, it can result in rupture, peritonitis and serious long-term complications.
Wrist injuries are regularly misdiagnosed in A&E settings, particularly scaphoid fractures, which can be mistaken for sprains. If not promptly identified, they can result in long-term pain, reduced mobility and arthritis.
Strokes are sometimes mistaken for migraines, intoxication, or even anxiety attacks, especially in younger patients. Every minute counts during a stroke—misdiagnosis can cause irreversible brain damage.
DVT can be misdiagnosed as a pulled muscle or general swelling. If untreated, the clot can travel to the lungs and cause a fatal pulmonary embolism.
Missed fractures are among the most common A&E errors, particularly when X-rays are not properly interpreted. Left untreated, broken bones may heal incorrectly, requiring more invasive treatment later.
Each of these cases involves conditions where accurate, early diagnosis is essential. When that accuracy is missing, the consequences can be significant and, in some cases, irreversible.
In order to bring a successful claim for misdiagnosis, we must demonstrate two key elements:
We must show that the standard of care fell below what is expected of a reasonably competent healthcare professional. This may involve reviewing how your symptoms were assessed, whether appropriate tests were carried out, or whether the diagnosis was made in line with current medical guidelines.
We must also prove that this breach directly caused you harm—either through deterioration of your condition, avoidable treatment, psychological distress, or long-term complications that would not have occurred with a correct diagnosis.
At PSR Solicitors, we work closely with independent medical experts to review your records and provide professional opinion on whether your diagnosis error amounts to negligence in legal terms.
Although no amount of money can undo the harm caused by a medical misdiagnosis, financial compensation can help to ease the burden and support your recovery. It can give you access to specialist treatment, cover financial losses, and provide the stability needed to move forward with confidence.
If your claim is successful, compensation may include payment for:
We can also advise you on whether a Personal Injury Trust may be appropriate. This can help to ensure that your compensation does not affect your eligibility for means-tested benefits or future financial planning.
Our goal is not only to secure justice, but to ensure you have the resources and support you need to rebuild your life.
If you believe you or a loved one has been affected by medical misdiagnosis, we can help you take the next step. Our team will begin by listening to your concerns in a free initial consultation. If we believe there are grounds to investigate further, we will obtain your medical records, instruct independent experts, and determine whether there has been a breach of duty and resulting harm.
We handle most claims on a no-win, no-fee basis, which means you won’t pay legal fees upfront—and you won’t owe us anything if your case is not successful. We’ll explain all your funding options in advance so you can make informed choices with complete peace of mind.

Your Medical Misdiagnosis questions answered
Yes. If your GP failed to recognise key symptoms, misinterpreted test results, or did not refer you for further investigation when it was appropriate to do so—and this led to harm—you may be able to bring a claim for medical negligence.
A corrected diagnosis does not necessarily mean there was no negligence. If the initial misdiagnosis caused your condition to worsen, led to unnecessary treatment, or resulted in physical or psychological harm, you may still have grounds for a claim.
Yes. If a loved one has died as a result of a negligent misdiagnosis, you may be able to bring a claim on their behalf. This can include claims for bereavement damages, financial dependency, or funeral costs under the Fatal Accidents Act 1976.
When a medical condition is misdiagnosed, the consequences can be serious and deeply distressing. Whether you were given the wrong diagnosis, treated for a condition you did not have, or had a serious illness overlooked entirely, the result is often avoidable suffering, prolonged illness, or irreversible harm. At PSR Solicitors, we are here to help you make sense of what went wrong and support you in seeking the justice and compensation you are entitled to.
From the very beginning, your misdiagnosis claim will be managed by a qualified solicitor with specialist experience in medical negligence law.

The effects of a medical misdiagnosis are not always immediate—but they can be lasting. Some clients come to us after suffering months or even years of worsening symptoms, only to discover that the wrong diagnosis had masked the true condition all along. Others are left with permanent injuries due to incorrect or unnecessary treatment that should never have been given in the first place.
In some cases, the emotional toll can be just as severe. Being wrongly told you have a life-threatening illness, such as cancer, can result in immense psychological trauma. Conversely, being falsely reassured that there is nothing to worry about—only to later receive a correct but serious diagnosis—can leave patients feeling angry, anxious and let down by those they trusted.
We regularly support clients who have had to give up work, undergo corrective surgery, or come to terms with reduced mobility or shortened life expectancy due to a misdiagnosis. In these cases, compensation can help relieve some of the pressure and provide access to vital support, including but not limited to:
While compensation cannot change the past, it can help you plan for the future with greater certainty—offering stability, access to care, and the support you need to move forward.
