Hi, As it looks like you are prone to muscle cramps every now and then of the lower limb region like the thighs and the legs, where leg cramps are easy to manage off but not the thigh one. Usually thighs don t get cramp, but in very few it occurs. Now muscle cramps are due to the sodium channels at the neuromuscular junction where the sodium channels fail to workout, you can try to take a pinch of salt and see if it works for you. Also, on term this may become more and may need to get examined. You should start getting involved in physical activity like exercises which helps the metabolic functions to come-up and avoid such channel blockages to avoid cramps and other symptoms. In case if it doesn t resolve with conservative management than try for some physician meet up and get it assessed with him. Hope I have answered your query. Let me know if I can assist you further.
