Is it wrong for a doctor to diagnose me for something that is irrelevant to my symptoms, which in the end is life threatening?

It is hard to say whether the ER doctor breached accepted standards of care by failing to perform a Doppler study to investigate a blood clot. Calf pain can be caused by a variety of different things, and while a blood clot is one possible cause, your patient history may have suggested other causes were more likely. If you were off of your feet for a period of time, or you had recent surgery, then a blood clot would be higher in the differential diagnosis.  Another question is whether your case is financially viable. Being on Coumadin for six months is a headache, but if you have no after effects following this, you probably do not have a financially viable case. If you want to investigate a case further, you should contact a local medical malpractice attorney (one in your state).  They take these cases on a contingency basis which means you only have to pay if you succeed.  Additionally, initial consultations are usually free. You can use the "Find a Lawyer" service through this website to research medical malpractice attorneys.  Then, visit each attorney's website and look for a firm that has a record of successful verdicts.   Below are some articles you may find helpful.  They are written for a New Jersey audience (where I practice) but the ideas discussed in these articles usually apply in most other jurisdictions as well.

I will do nothing further to protect or preserve your interests in the absence of any additional discussion with you about this matter. John Ratkowitz, Esq.
