your situation is alot like my husbands.
He had a huge mass from his ear to his chin that was out
wise the size of a baseball or bigger. He went to the ER
and like you was put on keflex the ER doc called it a
submandibular mass and said to get follow up care asap.
This was a ordeal with clinic doctors and dragging it out
to long. They also mentioned cancer and after sticking him
with a 19 gage needle said the mass was solid and not
fluid filled. He had a cat scan and a nodule was found on
his upper lungs and he was sent to a surgeon. The surgeon
first told us keflex was the wrong antibiotic
and that is why it did no good. He then knew right away
it was fluid filled and drained 3 containers of nasty gunk
first visit and almost 2 more on 2nd visit. It was not
cancer but one nasty infection/ cyst. He goes back Thurs.
to find out when they will remove it they wanted all the
fluid out first. They put him on two stronger antibiotics
and hubby is feeling great.
All in all for us
from the day he went to the ER it was drug out for 8 weeks
to get a answer the waiting was terrible. Most docs work
alot faster sounds like your doctor is moving quickly
Hope all turns out for the best. Is your lump tender? My
hubbys was and we were told that is a good sign. His felt
very hard but that is because of the mass of infection he
had I about threw up when I seen the gunk that came out
of him ** just flat out nasty
