Ever since I was a child I ve had these itchy blisters on the lower part of my back that comes and goes. They seem to be attacking higher each time the reappear and are leaving scars.

Hello and welcome to HCM,
Recurring itchy blisters on lower back are unlikely to be due to infectious cause.
The blisters seem to be due to non-infectious skin disease.
Are the blisters fluid filled?
If yes then these blisters could be due to pemphigoid.
Pemphigoid is an auto-immune disease causing itchy blisters on skin.
It may be associated with other auto-immune disorders and celiac disease characterized by allergy against gluten present in wheat.
However, this is just one of the many possibilities.
A clinical assessment by a dermatologist is necessary to make a diagnosis followed by investigations and thus management.

Thanks and take care
