[|Human|] I went jogging which I do all the time, but then after that I used a different kind of a machine. A T-Zone vibrator for 10 minutes. After which my calf muscle in my leg tensed up and got very hard. I tried to stretch it out. It didn t work. It was not very painful. The next morning a bump the size of a quarter rose on my leg in the same place where the muscle was. The next day, the bump went down, but left a red spot on my leg. Thank you for your help, Sue
[|AI|]  Hello, I read carefully your query and understand your concern. The symptoms seem to be related to a muscle strain. I suggest using a muscle relaxant such as Baclofen three times a day. I also suggest using magnesium supplement for muscle relaxation. Warm compresses can also be helpful. Hope my answer was helpful. If you have further queries feel free to contact me again. Kind regards!  Chat Doctor.
