what do ido about a blood clot inleg

It is difficult to give a specific answer to your question. First, if you have not done so already, you should immediately see a physician and get to an emergency room. It may be possible that the development of DVT, or blood clots in the leg, is a result of medical negligence, although that is not always the case. I would need additional information before I could advise as to whether you might have a medical negligence claim.
