My Dr. has put me on colcrys 0.6 mg twice a day. I had my left foot swollen all the time but also have neuropathy in both legs. Then I had a cataract removed on Aug 1st. The night before the surgery my left foot swelled up 3 times the size. By 1 AM I woke up in major pain and never went back to sleep that night. About 5 days later I went to the Dr and he put me on colcrys.
