<s>[INST] Hi, I used to masturbate daily once. sometimes twice...from 2 years. Recently (1 month back) I found that my left leg back of upper thigh portion is paining a lot. I am unable to walk properly. Especially morning, when I wake up it pains me a lot. I cant put a step to move further after i got up. My right leg is fine. Only problem is with the left leg. And I cant jump, run, cant do anything,.. only I need to walk slowly. if I feel the pain then I will stop and again i will start slowly. pain is always there in my left leg, based on my leg movement it comes suddenly don t know exactly when. Its really bad pain. I couldn t bare this pain. I stopped masturbating slowly. But pain is still there. I don t know if the pain is because of excessive masturbation or not?. Specially morning, it pains so much when I got up from the bed.. Please help me, what I should do to come out of this pain permanently. Why this has come to me recently. what is the cause? What is the medicine to use? I didnt consult any doctor yet. Do I need to take any medicine or shud I consult any doctor? Also, I didnt take any medicines. I am applying pain balm. Please respond to my query & help me. [/INST] Hello, As when you do masturbation there will be an isometric contraction of the muscles of the abdominal region, pelvic floor, thigh muscles and leg as well. Due to which there will be fatigue to set in, and muscles become over tiring and weak. Avoiding too much masturbation or in fact avoiding it for time being will be a good choice. Do simple exercises like walking or aerobics with low intensity and regain muscle strength and bulk back.  This is one of the commonest reason that after undergoing sex most people feel tired as maximum energy is being utilized. The best way is to have a good diet, water, and avoid masturbation. Hope I have answered your query. Let me know if I can assist you further. Jay In Chat Doctor.  </s>
