Bit my lower lip, now have what I think is a mucocele

Reading through the forums, decided to post this. I bit my lip chewing gum about 3 weeks ago, more than once. I noticed swelling in the bit area and then noticed what appeared to be a bump that was infected (raised etc). I popped it a few times only to have it come back and swell up. I decided to go so my Doctor who referred me to an ENT (seeing him today). Since Thursday of last week I have been using evening primrose oil, applying it 2 - 3 times a day. Initially the lump got bigger, I left it alone and kept applying EPO, it then decreased in size significantly, only to find it increased in size yesterday, after eating semi-spicy food. Very discouraging to say the least. I suspect I damaged some saliva glands as a result of biting my lip. I think EPO works great, but I would have expected to see more of a permanent response to using it rather than having the thing puff back up again.
 
Any advice on home remedies for similar situations such as this one?
 
Thoroughly frustrated,
