I have been using my hot water bottle for as long as i can remember, over the last year i have developed patchy some darker patches also of skin on my stomach, exactly in the spot where i hold the hot water bottle, i saw my doctor and he said it looked fungal, but fungal treatment does not seem to do anything at all, so im led to beleive it is a burn from the hot water bottle, i have scared myself into reading it can lead to cancer, what do i look out for, if it does start turning into cancer? The skin markings are not very severe and i have not been using my bottle for 2 weeks now and will not in the future, does anyone know of anything that can lessen the appearance of the skin pigmentation? Thank you for any help..
