Hi Cheryl,.
thanks for your kind advice.
Well, I have started applying the ointment.
I believe the 2 whitish hard "spots" on my lower left inside lip will be harder to get rid of with the ointment than the "grey" patch sore on the left underside of my tong.
The doctor was a bit young though.
I suppose she would prescribe the ointment before bringing up the heavy artillery such as biopsy, x-rays etc. if the prescription should not get rid of these symptoms.
Depending on her reaction I might ask for a second opinion.
As for the metallic sensation/taste I did not notice any blood.
Take care!
Warm regards,
Mike
