### input:
I have had this issue for 2 years and my doctors still aren t sure what is going on.My lower legs swell, are discolored, warm and tender, with pain shocks lasting only seconds. I have RA and had a tendon replaced in my foot 5 years ago. I had tests ran by a vein specialist, shows no clots, GOOD blood flow and heart beat. My doctor says no infection or diabetes. The vein specialist said leaking veins.This continues to get worse. I was taking Cimzia for my RA and have stopped for 5 weeks now under doctors direction. Still no relief. I have been taking methotrexate still for RA.

Hi I am Chat Doctor. .  From your given history your swelling could be due to an old trauma, cardiac or renal problems.  If your edema is bilateral this is a sign of underlying systemic disease if cardiac output exceeds its output (heart failure) or your kidneys cannot wash or flush your venous system .in rare cases your medication may cause such symptoms if used for long periods.  You have to maintain leg elevation, avoid standing or bending your knees for a long time and use hot foments with topical gels of anti-inflammatory.wearing compression stockings will be helpful to push up blood towards the heart and increase your venous return.  If you have not examined your arterial system by Doppler U/S you may need to check them up in very rare cases arterial system clots or atherosclerosis may occur and cause such edema.  I recommend full lab investigations and follow them up with your physician for proper evaluation and management of the exact underlying cause.
