Re: Back & Neck Pain
My husband had something like that in the arch of his foot after working on his feet all day. It would go down when off his feet but itched like mad. While on vacation, it would go away as he was off his feet a lot more.
It turned out to be the "belly" of a muscle that was in spasm so badly that it swelled up into this hard lump. The spasm had caused the blood to pool in the muscle "belly" so it actually throbbed and at one point, it was thought to be an aneurysm. Took an orthopedist to finally figure it out.
He was advised to put heat on it to try to relax the rest of the muscle and if that hurt too much, try ice first to reduce swelling and then try heat. The other thing he had him do was to take vitamin E. Don't know why but it worked.
Just my experience with something similar.
