This could be a lot of things but the hand rash and burning sensation is sometimes caused by liver problems. This individual needs to get their liver function checked.

The spike proteins are known to attack lots of parts of the body and liver is one of them. Quercetin has long been used to support healthy liver function and a few recent studies suggest it might also help limit spike protein damage, so that is something pretty safe that this individual could try and wouldn't need a prescription to do so.
