If you have bubbles, then you have blistered.
“Care of blisters
Home treatment may help decrease pain, prevent infection, and help the skin heal.
Small, unbroken blisters [less than 1 in. across] usually heal on their own.
* Do not try to break the blisters. Just leave them alone.
* Do not cover the blisters unless something such as clothing is rubbing against them. If you do cover them, apply a loose bandage. Secure the bandage so the tape does not touch the blisters. Do not wrap tape completely around a hand, arm, foot, or leg, because it could cut off the blood supply if the limb swells. If the tape is too tight, you may develop symptoms below the level of the tape, such as numbness, tingling, pain, or cool and pale or swollen skin.
* Avoid wearing clothes or shoes or doing activities that rub or irritate the blisters until they have healed.”
That’s from Web, M.D., which aslo gives the treatment for sunburn.
