Shingles is thought to be caused by a virus of the herpes family. It's basically the adult form of
chickenpox. A lot of people are scared of shingles because it can cause long term complications (pain).
These long term complications appear if you don't treat the shingles outbreak properly or early
enough. Many doctors send shingles patients home with just pain medication and no treatment.
A mixture of DMSO and IDU (Idoxuridine, an old antiviral drug) is a known good treatment for shingles (see https://pubmed.ncbi.nlm.nih.gov/1101247/, Idoxuridine in the treatment of herpes zoster, J R Simpson) but you are unlikely to get this if you visit a modern day doctor. Idoxuridine is a prescription medication.
Proper treatment disappeared when the Shingrix vaccine appeared on the market as a financially viable solution for doctors. Advertisements for this vaccine focuses on pain and fear. Shingles can however be completely pain free and benign if treated properly.
There are a number of effective but almost unknown home and over the counter remedies for
shingles. You can expect to get rid of your shingles outbreak in about a week if you start the treatment early. I would treat myself even if I just suspect a shingles case and there is no need wait for a professional diagnosis.
