Hi I'm being driven bonkers with my skin. I'm really anaemic, on b12 and iron due to super heavy flooding periods. Doc wanted me to have a transfusion 6mths ago but I've stuck with meds. I havent been great with them but my blood count has improved.
At the same time I had an all over rash, like hives. I was also getting skin ulcers and they took ages to heal, have scarred massively and left horrid dark pigmentation marks. It's been really getting me down as it's all over my legs, back, chest, torso.
Sometimes I felt they may be bites but I've checked for bed bugs, dust mites dont bite. I dont have pets. They dont even look like bites, but I'm just confused to why this continues.
A few days ago I'm on the sofa with my legs curled up under me...I felt a sting, my leg was sore in one place. As I was looking at it (and I couldn't see anything on my leg), I felt another sting about 2inches away from it. Again, nothing i could not see a thing in terms of bug but i definitely felt something. They weren't itchy but I was feeling one and then a tiny bit of skin just kind of came off 
The next morning they were both like mini ulcers/craters. Very much like all the skin issues I had before. Pic attached. Are they bites or is there something else going on...can anaemia do this? I was tested for celiac before as well and doc says that's all fine. I'm losing the plot and dont know what to do to fix this! Thanks for reading
