Miserable muscle pain in my right thigh that extends into my groin. On treatment for previous dvt...no swelling or warmth should I be concerned?

R/O DVT/RHABDO. DVT=Blood Clot would cause unilateral arm pain and swelling. If your mom has this she needs prompt evaluation. A Doppler US or LE will define the anatomy. Other conditions to evaluate are LYMPHEDEMA/RSD(REFLEX SYMPATHETIC DYSTROPHY). Also a full clotting W/U. You needs a prompt exam and through W/U. Check INR to evaluate treatment. CPK level to evaluate component of Rhabdomyolysis.
