Brief Answer:
Sterile bandage and home remedies

Detailed Answer:
Hello ma'am and my sincere apologies for the delay.

Thank you for writing in to us.

I shall attend to your query and try my best to address all your concerns.

First looking into the possible causes, blisters on the legs could be caused from repeated friction, burns (heat, chemical, etc.), infections (viral, bacterial, etc,) or other injuries.

As the doctors in your regimen are away, I am not sure whether you will be able to access medication or not so I shall help you with some home remedies.
-Keep the region clean and dry
-If I were your doctor I would first initiate a course of antibiotics (if you can get your hand on any, this will prevent the open blisters from getting infected)
-Avoid itching the region (you may wear gloves for the same reason)
-Lotions like calamine help in promoting healing
-Over-the-counter burn creams that can be used if this was caused due to a burn
-At home you could make a paste made out of oatmeal and baking soda which is quite popularly used in treating blisters
-Try the application of a sterile bandage (easily available in pharmacies) and apply it on the region of the blisters. These will require changing at least once daily.

I hope this information helps you ma'am. Please feel free to write back to me for any further clarifications and I shall answer your queries without further ado.

Wishing you a speedy recovery and god bless.
