When I thought I had a lump in my mouth last December, my hubby convinced me to call the dentist for peace of mind. (I too had spent way too much time poking at it, thereby making it worse.). My dentist squeezed me in THAT day. I was convinced it was a tumor, but after X-rays and a thorough check, he said I was perfectly fine-I was feeling bone and all the poking had irritated it. Sure enough, that bit of assurance was all I needed to stop touching it, and wouldn't you know? By the next morning it was gone.
Bottom line-see the dentist and put your mind at ease. A few hours wait won't be fun but better than a 2 month wait!!!
