I've got small lumps under skin all over body!

[Minkusis84]

It started in 2012, when i was in the shower, felt a small lump in my groin under my skin. It was hard, immovable, not painful or discolored. Then as time went on, they popped up everywhere, in my neck, armpits, groin, legs, and my forearm now as of last summer, a hard lump. None are painful, or anything. I have lost 200lbs in this 6 years, night sweats almost every night, bleeding often in my gums whenever i brush (Even switched to soft bristles...) and when i poo i have A LOT of bright red blood that comes out. Just the last 2 months things have been getting much worse. I've lost another 20+ lbs(now at 174lbs, usually i'm at around 200lbs), ive gotten even more tired and sleep a lot every day. I have this biting/stabbing pain in my left hip and then goes numb every time i lie down on my right side... it's new. I'm pale, tired all the time, fatigued, i've got peripheral nerve pain in my arms, and my legs even go numb when i lie down to sleep on my back. Not sure what's going on. I only had 1 biopsy of a lymph node from my armpit in 2014, but no diagnosis of anything. Been to the hematology lab, been tested in my blood for EVERYTHING you can imagine. Only problem on my blood tests the whole time is low platelets... So i'm not sure what's going on, but i definitely know something is seriously wrong lately, and i cannot find answers! I just recently got over what must have been the flu, where i was vomiting and bloody diarrhea for the week, along with more weight loss, hard to swallow anything, losing my appetite most days. My mother does have Fibromyalgia, but i suggested it to the doctor (VA hospital) and he didn't agree.
