My age is 25. Height 5 ft11imch. Weight 82 kg. Unmarried.from 2 years I am very ill. I used to have numbness and tingling in whole body, bone andmucular pain including mouth, bone weakness and muscular weakness, chest enlargement, belly fat enlargement too much. I used to have abdominal pain too since 2 years and I am also noticing a huge reduction in my testis size. All my body problem and testis reduction problem are increasing with time. My vitamin d is decreasing with time. In starting it was 114 (range 70 to 280), after 6 month it came 75 and now it is 60. My vitamin b12 6 month ago was 185 (range 180 to 900) and now it is 179. I took 5 injection for vitamin b12 but no improvement. My all test were normal except serum testosterone was coming in lower than reference ange from 2 years. It was 220 ng/dl or around. Then one month ago he diagnosed me with non obstructive azoospermia .he said you testis are small in size. But earlier they were big and I was noticing reduction. My ultrasound came normal and showing left testis volume 8 cc and right 9 cc. Then from 1 week I wad having black colour stool every time. So few days agp I had endoscopy ,it shows erosive gastritis and impression is fungal gastritis. Stoo occult blood was also positive. Now from 1 week I am taking medicine for it. From 2 days I am having blood in sputum. Blood quantity is equal to sputum. Then I visited to doctor ,he did my chest xray and report shows normal study. My question is that as my body qauuality degrading with time and I am loosing my bone health. Do I can have chances of cancer as I get bleeding in sputum and stool too?
