My son (9) got an abscess in his jaw a few months ago which had to be surgically drained because the antibiotics werent working (he was given an antibiotic that wasnt strong enough, then when he was switched to clindamyacin the infection was too severe for it to work) .  He got another infection a couple of weeks ago, this time, the antibiotics were administered in time and the infection went away.  It is not caused by a tooth, that has been ruled out.  He does have a swollen lymph node, which I know is common with infection, but he also has a hard immovable mass which seems to wrap around the lower part of his jaw bone, just in front of the lymph node.  I do have an appointment with an ENT, but it isnt for a couple of weeks.  I am just wondering if I should be worried about something serious.
Hello, I am glad that you will be seeing an ENT. An oral surgeon is another specialty that can evaluate a swelling in the jaw. There may be a cyst or chronically inflamed lymph node. The Andrew is an X-ray showing the jaw to disclose irregularities. Other causes are possible and further tests can be considered depending on the initial evaluation.  This may take additional time to resolve since you have reported multiple infections and difficulty with antibiotics. Thank you for your inquiry. I hope the area will improve shortly.
