My Doctor Misdiagnosed Me, and Now My Condition is Worse. Do I Have a Medical Malpractice Case?

medical malpractice misdiagnosis case

You went to your doctor looking for answers. Instead, you left with more questions. Misdiagnosed, or worse, dismissed entirely. Maybe they said it was stress, or that you were “overthinking it.” Now, your condition has worsened, and you can’t help but wonder—what if they’d just taken me seriously?

If your health has declined because of a doctor’s failure to diagnose or an incorrect diagnosis, you’re probably asking: Do I have a medical malpractice case? Let’s break it down.

When Does a Misdiagnosis Become Medical Malpractice?

Not every misdiagnosis is medical malpractice. Doctors aren’t fortune tellers, and some conditions are notoriously hard to pin down. But when a doctor fails to meet the standard of care—meaning another reasonably competent doctor in their position would have caught the issue—things start to shift into malpractice territory.

1. You Had a Doctor-Patient Relationship

If you sought medical care from a doctor and they agreed to treat you, they had a duty to provide proper care. This means they were responsible for your well-being and obligated to follow established medical guidelines.

2. The Doctor’s Mistake Was Avoidable

Doctors aren’t expected to be perfect, but they are expected to be careful. If another medical professional with similar training would have made the correct diagnosis, your doctor’s negligence might be to blame. This could mean they failed to order the right tests, misinterpreted lab results, or ignored obvious symptoms that should have raised red flags.

3. Their Mistake Made Your Condition Worse

A medical malpractice claim isn’t about punishing doctors for simple mistakes—it’s about real harm. If the failure to diagnose or misdiagnosis led to serious complications, a delayed diagnosis of cancer or irreversible damage, that’s when malpractice comes into play. For example, missing an early-stage cancer diagnosis can mean the difference between a treatable illness and a terminal condition.

4. You’ve Suffered Real Consequences

Lawsuits aren’t about frustration—they’re about medical expenses, lost wages, pain, suffering, and emotional distress that should not have happened in the first place. A valid misdiagnosis lawsuit must demonstrate significant damages—whether that’s permanent health complications, financial burden from unexpected treatments, or a decreased quality of life.

The Most Commonly Misdiagnosed Conditions

Some conditions are infamous for getting misdiagnosed. If yours is on this list, you’re not alone:

  • Cancer: A delayed diagnosis can rob you of critical treatment time, allowing the disease to advance unchecked.
  • Heart Attacks: Often mistaken for anxiety or indigestion—especially in women, leading to dangerous delays in treatment.
  • Strokes: If not caught early, strokes can lead to permanent disability, leaving patients with preventable long-term damage.
  • Infections: Undiagnosed infections in an emergency room can spiral into life-threatening sepsis if left untreated, causing unnecessary suffering and risk.

How Long Do You Have to File a Lawsuit?

If you’re thinking about legal action, time matters. California has a statute of limitations for medical malpractice lawsuits:

If you wait too long, your case could be dismissed, no matter how strong it is. This is why speaking with a medical malpractice attorney as soon as possible is crucial.

Proving a Medical Malpractice Case: Why Expert Testimony Matters

Winning a medical malpractice lawsuit often depends on expert witness testimony. Courts rely on expert witnesses—other medical professionals—to determine whether your doctor failed to meet the standard of care. This means another doctor will review your case and provide an opinion on whether the original physician acted negligently.

Take Huffman v. Lindquist (1951): The California Supreme Court ruled that doctors can be held liable if they miss a diagnosis that a reasonable physician would have caught. Or Landeros v. Flood (1976), which held that failing to diagnose and report obvious abuse had serious legal consequences. These cases highlight how medical negligence can have devastating results and why expert witness testimony is so critical.

What Compensation Can You Recover?

If your medical malpractice lawsuit is successful, you could receive compensation for:

1. Economic Damages

  • Past and future medical expenses, including surgeries, treatments, and medications.
  • Lost income due to time off work and potential loss of future earnings.
  • Rehabilitation and therapy costs to help recover from the damage caused by the wrong diagnosis.

2. Non-Economic Damages

  • Pain and suffering from prolonged illness or unnecessary treatments.
  • Emotional distress caused by the stress of dealing with a worsened medical condition.
  • Reduced quality of life due to preventable complications.

California caps non-economic damages at $250,000 under the Medical Injury Compensation Reform Act (MICRA), limiting compensation for pain and suffering, but economic damages are not capped.

3. Punitive Damages

These are rare but possible if the doctor’s actions were reckless or grossly negligent, such as knowingly ignoring critical symptoms or falsifying test results.

What Should You Do If You Suspect a Misdiagnosis?

If something feels off, don’t ignore it. Here’s what to do:

  1. Trust Your Gut & Get a Second Opinion – If something doesn’t feel right, see another doctor. They might confirm or correct your diagnosis.
  2. Gather Your Medical Records – Keep copies of test results, prescriptions, and notes from every visit.
  3. Track Your Symptoms & Expenses – Write down how the medical misdiagnosis has affected your life—physically, emotionally, and financially.
  4. Talk to a Medical Malpractice Lawyer – A good medical malpractice attorney can help you figure out if you have a case and what steps to take next.
