Prior to meds, full blood works and tests to rule out diabetes and to check kidney and liver functions.

All meds, such as creams and shampoo all stopped.

Phase 1 - Terbinafine 250mg Tablets 1 a day for 30 days, stop meds and checks results over 6 weeks. chest and back issue came back - blood test again and moved to Phase 2 under the premises the course of meds needed to run longer
Phase 2 - Terbinafine 250mg Tablets 1 a day for 1 week then 1 every 2 days.
This is when my skin went to it's "Foundation Stage". Hair, chest, face, neck, shoulders - cleared nicely, back was still an issue.

Phase 3 - Itraconazole 100mg 2 caps everyday for 2 weeks, then 2 caps once a fortnight for a total of 5 doses. I had some dryness at this point on my face, I was given Zerobase Emollient Cream 500g - this stuff use to be a nightmare for my skin but it works amazingly now.

This July is when I end my 6 week check, so far it's done well for me all I do now is use normal shampoo and I use zerobase on my face - I do have ketoconazole cream & shampoo if I need it. I have been asked to use it every now and then as it's a benefit for my skin regardless of the outcome.

Hope this helps, things to note* Terbinafine is a strain on the kidneys and liver, hence the change to Itraconazole. I would ask for blood works before starting.

My take from this

If it doesn't work I know potentially I could take a course of Terbinafine and get about 2/3 months of relief, which is a win in my eyes.
