Hi, Thanks for posting in HCM. I understand your concern. Masturbation is a healthy and normal physiological phenomenon. It helps to get rid of old and stored sperms and makes way for production of healthy fresh sperms. It does not cause any adverse effects on the body like physical weakness, mental fatigue, premature ejaculation or erectlie dysfunction. Intact, it also helps to relieve mental stress to a certain extent. However, it should be spaced well and should not be done too frequently. Hence, what pain or discomfort you are experiencing might not be related to the masturbation. You can take simple analgesic medication like Ibuprofen to overcome pain. Also supplementation of calcium through diet in the form of milk everyday and medications like calcium syrup or tablets regularly will be beneficial. Hope the information provided would be helpful. All the best.
