I have had small irritations under my skin that show up as a little red bumps on the skin surface, that will come and go in about a weeks time. They are itchy and nothing appears on the surface. Today one is visible and looks like a zit, this one, in particular has come and gone maybe 2-3 times in the last couple of months. Every time its red and itchy? This has been happening in multiple areas around my body maybe 4-5 locations. I have not changed deodorant,soap,detergent,etc... Any thoughts?

First thought, scabies.

But really it could be a million different things.

See a doctor. They will be able to tell you what it is.

The only reason I say scabies is because our family had an outbreak a couple of months ago. They started the same way you have described.

Could be allergies as well, a reaction to something new in the air. Could be a parasitic infection. Could be a number of things. Have you seen a dermatologist about this?
