Welcome to Healthcare Magic
You probably need to get addressed as to what caused the clot and take precautions to prevent this from happening again. You may require blood thinner if there is a problem in your blood. Eat plenty of fresh fruits and green leafy vegetables. Drink enough water. For nerve pain
medicine like Gabapentin
may work but if the pain is severe you may require opiates like morphine
or even surgery to remove the painful nerves. Consult your Doctor in this issue for your relief.
