(male 5'9" 200lb) this may or may not relate, but i had a weird feeling when i pressed my gut against something...felt a weird sensation bordering pain and the feeling of urination straight through my gut, pelvis and penis. it seemed to start from my bellybutton after some poking and proding. then after about a week or two the feeling certainly became more on the pain threshhold and i'd actually have to go urinate. i felt around my bellybutton and on the top part of it inside my belly i could feel a lump and pressing on it would create this sensation. so i took a peak around, and moved my bellybutton around, tried to open it(i have a deep button) and saw a few hairs poking out. so i grabbed some tweazers and pulled them out, they weren't attached and came out ok. (i took care not to push tweazers too deep) then moved my button around some more and found a few more...i dug away and pulled out maybe 30 or 40 1-1/2 inch long hairs, the deeeper the hairs, it seemed to accumulate what i can relate to the most as yellowy puss. i did what i could, shaved around my button and dipped a q-tip with salty water(i had no peroxide) and dipped the outsides and first 1/4 inch of my bellybutton massaging the water into my button hole and hit the hay. the next day, the pain was still there, but lessened and couldn't really see any hairs within the first 1/2 inch of the hole. later i had a shower and took another look, i found a MONSTER wad of hairs covered in what again i think was puss. i pulled them out(one big wad) and within 15 minutes my stomach was feeling at least 80% better. i'm thinking with time and lackluster hiegene, hairs will accumulate and infect you bellybutton... posting is gross i agree, but holy hell i was sh**ting my pants when i felt the lump and weird sensations...thought it was cancer or something. hope this helps someone.
