Skin colored bumps that itch all over my body!

I have had a "rash" for 3 weeks. I went to the doctor several times and they cant figure out what it is. First they said it was an allergic reaction to something I was using. So I was precribed a steroid pack (oral pills) and a steroid cream. Neither of which did anything other than make me gain 6lbs.:-/. The rash consists of these very small skin colored bumps that started on my hip then slowly spread to my side and then now 3 weeks later is all over my body except my face. Each bump is about half an inch away from each other. Some are clustered together. Ive considered chicken pox but they dont have blistered tops. Not scabies or bed bugs, I've had an exterminator come and check my apartment. Also the bumps itch like crazy! Sometimes my arm will itch and there wont be bumps but once im finished scratching there are some risen bumps. My dad has a history or ezcema but the doctor ruled it out.on my legs it looks like heat bumps or small ingrown hairs but thats not either because there is not puss and they are not red. On the rest of my body (mid stomach area) they look like mosquito bites before they swell from scratching and on my chest it looks like zits without white heads and under my arms it looks like a mix between rosasia and mosquito bites. I cant stop the itching and they just keep spreading! please someone help me!

If it's something you're coming in contact with that you're allergic to, you may get some relief from a bath of colloidal oatmeal. Make sure you get the product intended for a rash and not the cosmetic skin treatment.

Me and my 6 year old daughter have similar bumps. They are skin color until we turn red from scratching. They don't tend to be in clusters. Most are spread out and appear in certain areas at a time. Right now I have one on my wrist that is giving me the devil itching. This is one on my back, my ring finger knuckle and a few on my thigh in different spots. Last week they were on my lower abdomin spread all the way across the front and some on my butt. My daughter tends to have them on her lower legs and ankles. Thankfully hers have not spread like mine. We went to the dr. and they told us he had no idea what they were but they definitely were not scabies but that they appeared follicular. I don't know what this is but they are driving us crazy. PLEASE HELP!!!!!

Maybe poison ivy
