I am traveling in Greece right now and got myself a serious sunburn after day one. My skin had been feeling very strange (kinda rough as if I had sand on it) after the burn, and this morning I had all these blisters. They don’t hurt or anything. I sometimes get Sun rash bit it looks very different, is this like a first-degree burn or what? I used a needle to pop one, it burst very easily, some fluid came out, no pain and it’s like nothing was ever there (but skin still feels rough), so of course I am thinking about doing the same to the rest of them but I am afraid I am making it worse?
