I recently got a implant done, but during my healing / antibiotics stage – my tongue started to appear like I have oral thrush (white hair – very sticky, and can be scrubbed off with no pain). Red dots all around an large bumps at the back of my tongue. This is no where else in my mouth but my tongue.
I was prescribed Nystatin, but it did not work. I was recently prescribed another mouthwash similar to nystatin but nothing is changing with my mouth. There is no pain anywhere else, minus the odd muscle pains in the legs (started about a week ago).
I also just noticed that I have white scars on penis. I’m not 100% sure when this started, but I noticed it in the last couple days. There is no pain and the scars are about 1mm in dia and are on the shaft of the penis and balls.
Is there something more that I should be worried about?
