Glad you found out it was only a bone. My ENT removed a healthy tonsil before informing me that it was a bone - a normal pillar! It was months before I could sing again! So glad your doctor was smart and didn't offer to remove your tonsil!
Seen doctor today peeps, said it's a bone and not to worry. Take her word for it I guess, we're all different. Glad its not a tumour but was told a tumour does not present as a bone texture. Keep it simple if it feels like a bone then its a bone! Thanks for the advice and comments it's much appreciated.
I "found" that hard as a bone "thing" back there too and went to an ENT (ear, nose & throat doctor.) He scheduled the removal of a tonsil and afterwards informed me that the pillar back there is normal! Leave it alone it is part of the pillars that grow from your thyroid and parathyroid glands.
