Is this folliculities or something else?

I got small and tiny watery blisters very itchy with a itchy and burning skin in legs and arms and in some areas look like a rash.
I saw a doctor who was very confused about my 'rash' so he couldn't prescribed anything until I see a specialist but I was in such a torture from the itchy and burning skin that finally he said it could be folliculities so he prescribed antibiotics.
I started taking the antibiotics and after five days I could feel some relieve and I could see the blister drying out and shrinking slowly.
I took the antibiotics for two weeks as he prescribed and I was cleared of all the itchy blister so I was happy that I was cured even if I was feeling sick from my stomach from the antibiotics but two day have past since I finished the antibiotics treatment and the itchy blisters and burning skin is coming back.
I haven't see any pus or materia in the blister which is sign of an infection but I figure since this rash I got responds to antibiotics it means I have some kind of bacteria infection but for what I read it doesn't look like folliculities.
I will see a skin specialist in two weeks finally and I hope he have some clue about it.
In the mean time what do I do, I feel so sick of my stomach that I don't want to take more antibiotics, but I have to do something for the itchiness and burning.
A natural treatment is my inclination and agree better with my body.
Any ideas in what is this rash I have.
Any similar experience to share.
Thank you for your time.
