If you have a sports injury, you can take
medicine to reduce the inflammation. I mentioned staying out
of a hot tub. I just want to say that I would only do this if your doctor hasn't mentioned anything to you yet. If your doctor tells you to take warm baths, then go with whatever your doctor says.
I doesn't sound like MS. In the remote possibility that you do have it, it doesn't mean that you won't be walking, or even that you have to quit lifting.
