Im having pain in my legs, thigh and calfs also been feeling very tired and short of breath and going short distabces and up the stairs. also pain in ribs?

Doctor can evaluate: Chest pain and difficulty breathing are signs that she should talk with her doctor right away or go to the ER. She should not drive herself (call for an ambulance if symptoms are more than slight). Aside from a deep venous blood clot, other possibilities are an abnormal heart rhythm, myocarditis, anxiety attack symptoms, a collapsed lung, pneumonia, etc...
