I've had sinusitis for over a month and tried all the over the counter stuff, steaming, compresses.. nothing's worked.
Finally managed to get a doctor's appointment and was prescribed a 7 day course of amoxicillin. I can't remember the last time I had any antibiotics so can't gage when I should be able to smell again!!
I'm only on day 2 with no improvement, super impatient. When did it start working for you?
If they're being effective, you can notice antibiotics working in as little as three hours. I've had this with a root canal infection. However with an excruciating ear infection it took 48 hours during which I was unable to eat, drink or sleep
Sinus infections can be hard to shift. I would say if you've got no improvement by the end of tomorrow, you should see your doctor again.
I had similar recently and they didn't work as quick as they usually do for other things. Gradual improvement over about a week. It took another 10 days probably to smell again. I think its because although the infection is gone, all the tubes are still blocked and there isn't an easy way for it all to drain away quickly. That's my theory anyway, not based on anything scientific!
