Patient's question:
Started masturbating in middle school. Now sometimes my lower back hurts really bad, but it only lasts for a short time, then it's fine. Before, when my penis was erect, it felt very full and hard, but now it's getting softer and softer, and my scrotum is also easily sweaty.Doctor's answer:
Cold body, slippery sperm during sexual activity, backflow of sperm, dizziness, fatigue, insomnia; if you have lower back pain, you should consider whether it's kidney deficiency.
