I'm masturbate for 5 years heavily. 2 months ago ifeel constipation &go for stools 3-4 times. My stools are pulpy.sometimes stools are very thin with small water. After flush out stools were broken in small pieces every time. I feel pain in legs &feel all time tiredness. I loss my appetite by half of my food. Sometimes I feel burn on my lips& another taste of mouth &tounge. Ihave a pain in lower back & front side of stomach. Sometime ifeel pain & sometimes not. Due to this acne comes on my face. Is it a sign of death or big dieseas or kidney, liver, pancreas diseases .
