I have a rash/ bumps (the bumps looks like small burns with blisters) behind my ears and along the back of my hairline. There are sore areas ie behind left ear and in center of neck at hair line that are swollen and sore. There are small bumps, not red, flesh colored, which itch going down my back and I have just noticed them on my cheek. I noticed them on Saturday. I have used tea tree oil, kamani oil, manuka honey, h2o2, and have just tried a cortizone and over the counter anti fungal. I live in the jungle/ rainforest of Hawaii. Any thoughts?
