My legs and feet are very swollen. They hurt and there are little bumps all over them. Legs and feet are red. Been in hospital frequently with Autoimmune Pancreatitis . Also have Renal Tubular Acidosis and high blood pressure. I take Prednisone, Potassium, Sodium Bicarbonate , Clonidine, Amlodipine, Oxycodone, Hydrocodone, Omeprazole. Legs and feet always swollen after hospital stay, but never this bad or for this long, and they have never hurt like this with the redness and bumps. Is this a side affect of my medicines?
