Ladies, I went to my family doctor 3 times who said she found nothing, until the 3rd time, when she said it was a canker sore. This was after several months of going to see her. I ultimately ended up with an ENT who confirmed tongue cancer. At that point, the tumour was visible, and growing rapidly.
All I can say is we know our bodies better than anyone else and we know when something is wrong. If you think something is wrong, keep at it. If it turns out you are just paranoid, so be it.
Best of luck that you are just paranoid, but if not we are here.
