I went on holiday to Tenerife with no pain what so ever. I went into the swimming pool which had a strong smell of salt... I have also been using new bodywash which is very sented. Since I went into the pool it really hurt to pee. I then noticed I was itching quite abit, and that I had a few little spots that have turned into blisters well look like that away... with like a blistery head on them I am in so much pain when I wee and move. My walking is becoming very slow aswell. Any advice ?? What could this be.
