Had a sudden moment of inspiration last night

I think a good candidate for what I might have is candida overgrowth.

I have had sweat rash (same fungus) on and off for months.

I also had several antibiotics right before all of this started 6 months ago for a variety of things

This would also explain all of my symptoms including the heartburn and stomach discomfort which could not be explained by any other ideas.

Going to see the doctor next week and get them to test for it.

So grateful to everyone who has posted here been a real comfort will let everyone know how the results come out.
