|I used rubbing alcohol on my blisters with great success.
It rapidly dried them up and made things alot better.
I tend to et it early winter/late winter, when the soil is still damp, but temperatures jump up and down with the changing season.
Try rubbing alchohol, and dont be afraid to overdo it, I userd it wih phenomenal success, Also, it removes the liquid it weeps out.
I have poison ivy right now on my right leg. I contracted it friday. Todays sunday. Its weird. it jsut looks like a raised bump of skin, its like it skipped the whole rash stage, i hope i dont jinx it by saying this. But it just looks dried out right now. It itches like hell though.
