I have had edema in my legs for a long tim (overweight.) Recently, my doctor prescribed a water pill and the swelling in lower legs is going down. But now I have pain and tenderness in upper quads, some warmness, etc. Could the water pills be causing this? Should I worry about a DVT? The pains started the other night when I was sleeping- in the areas I was putting pressure on. Since it is both legs, and no redness in the area, I thought more likely electrolyte/muscle vs. DVT. Thoughts?
