I don't think you should do any home treatment, or any treatment not prescribed by your doctor.
In fact, NO treatment until these spots are biopsied for the lab.
You have had them for years.
They are no psoriasis, they do not look like eczema, and certainly not fungal.
They are probably autoimmune, but from what condition.
A simply punch biopsy will show if these are
rare skin condition
That is what you should do next.
