Hi. My left leg, and occasionally my left arm, swells to point it s too painful to walk. I ve seen 2 doctors, tested for gout, ultrasound for arteries in leg, both fine, no gout, no blood clot. I ll be seeing a vein specialist soon and Dr is running me through more blood work. Maybe a Guess at what Dr can check for? No new meds, I m 60 yrs old, female, general good health, and totally quit smoking recently.
