hi, thank you for providing the brief history of you. A thorough neuromuscular assessment is advised. As mentioned about the discomfort in the leg and thigh a thorough assessment is advised based on which the treatment plan will be made. Also, avoiding self medication is recommended. As you have taken medicines - it is legitimate that it may cause some symptoms of acidity , due to which you are having a pain in the left hypochondria. The first thing to do is to stop medicine and see if the symptoms subside. Also keep body hydrated and consume more water with cooling food. So the acidity comes down. If by stopping medicine the pain comes down in the left hypochondria then it was a side effect of the medicine. Also, for the discomfort in the lower limb you can get assessed by an ortho. Performing neuromuscular assessment and special test we come closer to diagnosis and also help further. Along with proper physician prescribed medication and physical therapy the discomfort can be relieved. Regards Jay Indravadan Patel
