I had surgery on a torn meniscus and ganglion cyst two and one half months ago. The incision on the inside front side of my knee never completely went down but there was no pain. Lately it is more swollen and there are shooting pains when I walk. Also, the swelling seems to have travelled down the front of my knee about one to two inches. I have been exercising on the elliptical about 15 minutes every other day. The shooting pains are not with every step but very often.
