If blisters on palms and soles with some on the sides of hands and feet, I suffered for 15 years. For some of us with alergies this is an overactive immune system. Mine triggers bad on raw cashews. Watch what your eating.
Topical creams didn't help, also Never pop blisters... You risk infection, that landed me in the hospital once. Wear clean socks and change a lot. Non colored socks.
Best solution for me...
Prednisone pills. 5 day one, 4 day four, three day three, down to 1 and your blisters should dry, skin soften and hopefully clear and repair till the next outbreak.
At times both my feet had small bumps that grew and fused together till I had one big blister covering each of my soles.
Prednisone was prescribed by a doctor and has to be, see your physician and ask for it.
It is a steroid but if you are like me it's mild use maybe twice a year is a life changer for the better.
Hope this helps
