Just a quick note to say hi! You don't know me but I have the same problem. CTs, rinses, washes,dental checkup, ent, everything. Went to Dr. yesterday, same office diffrent doc, said it "possibly" staph infection,prescribed sulphameth/trimethoprim. x2 a day, took one at 8 last night hour later I could feel things changing in my nose. took 2nd pill this morning smell is disappearing,. he also had me follow up with different ent. appt next week. but so far in 12 hours I've already seen a change (as in how other people react to me when I come around) and how my nose smells when I cupmy nose and mouth. Hope this helps. I promise I am NOT joking!!!!
