This was my 3rd visit to the clinic for the same condition that did not improve after two attempts with the treatment prescribed by the nurse practitioner.
On my 3rd visit I saw the doctor and and it turn out the reason the treatment hadn't worked.
Now,
Before I continue I want to make something very clear.
The 2 gentlemen I saw on my first two visits were both great.
It turns out I had rare condition,
that required special treatment,lab work, and a referral to a Dermatologist.
The doctor was amazing,
I have mental health issues and the understood,
was patient,
and explained everything in way that I could understand clearly
