Hi,I may have scabies, I have been itchy and got blister looking pimples all over my arms, chest, stomach and back. I have used two creams that is for scabies and I haven t had any luck. I have been having bath with bleach, pool salt and bath oil. That sooths the itching. I also have antihistamines. But during night time I m extremely itchy. And I don t know what else to do. I have bought tea tree oil,d dettol antiseptic, rubbing alcohol. But unsure what to use.
