Ten days ago I had a biopsy done on a mandibular cyst. At that time, a drain with grommet was inserted. What is a typical recovery like after something like this? I feel like I have a constant canker sore (not getting better), and there is still some swelling a little above that area that feels like a marble and is tender to touch. I have been flushing the drain 3 times/day with salt water and some bloody saliva still comes out when I start the flush. I see the surgeon again on Thursday to get biopsy results and, hopefully, some resolution to this pain. Any advice is greatly appreciated.
