[|Human|] I have a sudden pain in the back of my leg at the top of the right calf. I am not a runner, biker or was doing any exercise at the time. When I bend it, there is a sharp pain. I noticed it when I was walking down the steps. There is no swelling or redness. What could be the cause?
[|AI|]  Your symptoms suggest that you have spasm of gastrocnemius muscle. It occurs due to unnoticed sudden jerk at knee while climbing stair or unsupported standing from sitting posture. But you need not worry at all. Rest, anti-inflammatory analgesics such as ibuprofen and muscle relaxant such as thiocolchiside will help you in reducing pain and spasm. It will take 5-10 days to heal completely. Hope this helps. Hope this answers your question. If you have additional questions or follow-up questions then please do not hesitate in writing to us. I will be happy to answer your questions. Wishing you good health
