My 90 year old aunt has pain in her left lower leg, and has had this pain for some time, she has been to several different Drs, along with a pain management team, she is on oxycodone 7.5 mg q6hrs and continues with pain, I think she has PAD, her feet are always cold, it s hard to obtain pedal pulses, the Dr has her on a medication for neuropathy that is not working, should she go to a vascular surgeon?
