Back pain can occur due to age, illness or injuries that may have occurred in the past. Although, it is definite that excessive masturbation causes back pain, mainly of the lower back. So why does this happen? Masturbation is good for your health. Believe that, but excess of this practice is disadvantageous for your body. People often experience mood swings, erratic sleeping patterns with soreness of the back. Those are some of the signs that the cause of your back pain is excessive masturbation. Cramps in the pelvic region or the lower back, insomnia and erections that are becoming harder to sustain are some other symptoms. So how does this really happen? The over ejaculation process depletes your brain of acetylcholine, dopamine and serotonin neurotransmitters, leading to a sympathetic nervous system reaction. When this happens, this sympathetic nervous system burdens your liver, endocrine system and cardiovascular functions leading to inflammation that causes your back to hurt. Hence, the answer is yes. You should definitely go visit and consult a doctor if you are going through a similar condition.
