question: Hi doctor, I am 24 years old male and I have problems with my joints specialy knees cracking sound and little bit pain when I take the stairs or put a pressure on the knee. I feel it is related to masturbation because every time I masturbates the symptoms increses and the pain increase, even though I read about it and someone asked the same and the answer was its not related. Please tell me what to do about it and is it related to masturbation or not ? Best regards
