swollen ankle

So for weeks before I had radiation and everything, my left ankle was always swollen. Same side as the cancer in my pelvis. Accompanied by shooting pains down the inside of my leg. I hadn’t really gotten an answer as to why it was happening. The swelling went away and I thought it was the radiation that fixed it. Apparently not. It’s swollen again. I guess it’s all the walking I do at work that’s causing it. Whatever the “it” is. So far no shooting pains down my leg. I’m going to have to try and walk less I guess.
