Usually, people get relief from the itching by taking large amounts of the enzyme protease. Some people have taken 20 per day. There is no overdose limit. Others find relief in topical application of ozonated olive oil, or colloidal silver, or even emu oil. However, nothing works for everyone.
Some people just have to grin and bear it, knowing that there is a reward at the end of the ordeal.
I am about to start daily ozone sauna treatment.
