Carpet beetle rash?

I woke up about 3 weeks ago and noticed tiny bumps all over my stomach.  After a couple days, they began to get itchy, then a rash developed under my breast and my left arm pit.  I started to think that they were bed bug bites, but the exterminator found only carpet beetles.  I have always been allergic to bug bites and I was the only one in getting bitten.  It started to go away over the past few days, but the rash then started to spread onto my neck, my lower back, the center of my back, and across my shoulders.  It is extremely itchy, and I do not have insurance to go see a Dr.  The rashes on the front of me have started to go away slightly, but my armpit is getting worse, inflamed, and surrounded by small red spots.  They look like small zits.  

I have looked up different types of rashes, and aside form the severe itching, I have tried hot water, calamine lotion, witch hazel, rubbing alcohol, vaseline, and a few other things, but nothing makes it heal faster.  I am going on three weeks and it is starting to freak me out.

Hello,
These can be insect bites, viral rashes, contact dermatitis or folliculitis (although less likely). Use a mild cleanser with moisturizing properties like Cetaphil. Also use cotton clothes and change the clothes twice if there is any increased sweating. Try keeping the skin free of sweat as far as possible. If the symptoms still persist then you can apply mild steroid like dermacort. If there is any itching antihistaminics like Benadryl or Claritin can be taken.
If the symptoms persist then get it evaluated from a dermatologist.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
