I had hip surgery in February, its healing fine and no pain. But about 3 weeks ago I began retaining water in my hands, legs and feet. Also I have intense joint pain in mainly my hands/knuckles, and my knees and I don t know what the cause is. I should also mention, I have been treated in the past year for Ulcerative Colitis, so I am already on an anti inflammatory med called Simpony. What else could cause this? Should I see a doctor?
