I just happned to log in today!
The pain post op was not as bad as the biopsy at all. The biopsy was very painful I could not eat for almost a week. I think when they carried out the main operation on my tongue, they used a laser. For the a biopsy they used a scalpel as far as I know. I was told the laser burns and cuts off the nerves which really decreases the pain. A knife does not, hence it being more painful for the biopsy. Overall the tongue operation was not too bad, it is just a matter of getting used to the new feeling in your mouth, slowly getting used to eating again and being patient why it heals. It’s been four years and I still get occasional tinging sensations in my tongue, the nerves are still healing. It just takes time like everything. Speech has been the main thing I have to work on constantly. You find yourself trying to talk like you still have a full tonuge, and have to remember to speak slowly and make sure to make full use of your lips to improve speech. But I can't complain, it doesn't effect me too much these days.
All the best!
