Pain in side and back upper thigh muscle, getting mild shocks and also discomfort in walking. What should I do ? Pain started last evening, was slightly better morning but again increased from evening It's difficult to walk straight and the upper right thigh is paining. Not sure if nerve compression or muscle pain, had done light exercise yesterday morning and was in office all day, from last evening pain started randomly, haven't had any fall or any other symptom like this.
