I had a upper rspetory and head cold. It heald on for about a week before going away. I did take the Z pak. Two weeks later I had swollen glands in my jaw and was precribed amoxicillin. I am on my fourth day and I still have a lima bean size lump under my tongue along the jaw line. The glands have gone down in my jaw but this still remains. HELP! I cant wear my dentures because of this thing, without alot of pain.
