Worried

I'm not sure if anyone can give me any advice or wether I should be even posting on here as I would hate to be wasting people's valuable time , especially on a site that deals with such serious matters ,  but I'm scared , so here goes .... in the last 5 years I've only left my house 8 times , I have severe ocd , I've had it all told for around 15 years but like I say only in the last 5 have I been pretty much completely bedbound , I have no contact with the outside world an struggle to do even the simplest of tasks such as going to get a glass of water shower etc , I'm not exaggerating when I say nearly everyday for five years I sit silent in a room just looking at the 4 walls , obviously massive depression and anxiety comes with this not to mention horrible intrusive thoughts that pretty much paralyse you for weeks at a time ,  terrible diet etc.... anyway I've  noticed I have alot of tiny lumps in my abdomen , some small and others a little bigger ( maybe like the size and shape of a walnut ) you can't see them but you can feel them when pressing down , some are closer to the surface of the skin and they are the ones with the most movement  , others are deeper inside with less movement , some are harder than others why some feel softer , some are tender why others don't have any pain  , I've been pressing and touching them for a couple of months especially the ones that are deeper in my stomach and abdomen , they have become painful ( like a constant burning gnwaring  pain ) and also when I move postion or breathe in or out deeply I'm now getting very sharp stabbing pains in my abdemon , there are single ones and also groups of them close together  , I've also been getting bad lower back pain that radiates all the way to between my shoulders and shoulder blades and neck pain , although I'm literally always laying on my back and my neck is always bent forwards up against a pillow and I think that causes alot of pain between blades and upper back and lower back pain is alot worse when I stand , I've read about limpomas and swollen lymph nodes and am just wondered if all my proving and pushing has inflamed or aggravated them ? I hope I'm not wasting anyones time I'm just really scared , thanks
