You have wats called chigers sand mites
Hello,
These itchy bumps can be due to allergies, viral infections or scabies. Scabies is an infestation by the itch mite. Scabies produces small red bumps and blisters and affects specific areas of the body. Scabies may involve the webs between the fingers, the wrists or other folds of body.
I feel that you should get it evaluated from a dermatologist. Diagnosis of scabies is made by scraping the skin and viewing the material under a microscope to see the characteristic mite or eggs.
I hope it helps. Take care and regards.
