The back of my leg, right behind the shin has a so called mouse, that looks like a swelling of the muscle. I had already consulted 2 doctors on this problem but they have no clear opinion. The only concrete thing they can say it a pulled muscle so I should not engage in strenuous physical activity. The appearance of the mouse is continual, like now you see it and tomorrow it's gone. The only remedy for now is the hot compress where I place my foot on a pillow and the hot compress underneath. That session takes 5 minutes and the muscle would be relaxed. Any opinion on this? I would want to post a pic but I get an error in uploading.
