Ichy Skin??

I have these itchy spots on my arms and legs. Most of them are only just red bumps, and few (2) are actual blister bubbles. They are mostly around my ankle and few (3) are up near my knees, and there are four on my arm. I own done some research online regarding possible scabies or other cause. However I cannot find a sure answer since mine are spread out, and they are only on my right side such as my right ankle and right arm. I enjoy none on my fingers or my palms or my feet. They are extremely itchy, and they singular showed up two days ago after I was drawing my sidings on my roof. Is it possible that I'm allergic to my roof. Or that something up there could hold bitten me?Ichy Skin??
I actually get the same article on my elbows and knees after I painted my renovation house. I went to the doctor and he said it be a reaction to the paint and it dried out and irritated the already dry parts of my skin and cause irritation. It's not scabies, those are around waist and wrists and ankles. I got some cortisone ten cream beside moisturizers and it was gone within a week. Good Luck!
Take an antihistamine and see your doctor.
In the meantime, dont pick at them and try not to scratch them. If the itch get to be too much, use an Oatmeal bath similar to Aveeno.
could be psoriasis. go to a dermatologist,

It could also be you came contained by contact with some fiberglass if you own shingles on your roof ?
