My mother is facing pain while walking even for 10 or 20 mins. (Normal Walking). She told me that she has pain in her thigh muscles only in left leg and due to this she will not be able to walk any more. But once she sit down for approx 10 mins the pain will starts decreasing. This problem starts from last 1 month. Please suggest me what to do or which specialist doctor is right choice for this problem. Or which medicine is right for this problem. One more thing she has gastric issue if she had some alopethic medicines.
