Hi, with such presentations on my clinic I would first check your nose independent from your
Knee replacement operation.
1. The most common thing for such problems is an infection like
acute sinusitis. In this case in the endoscopic view of the nose it should be pus flow.
2. If you have problems with your nose breathing and frequently sinusitis maybe its a conical sinusitis. In this case the sinus mucosa protrudes into nose where the smelling column is located and so that you can't smell properly.
3. When there are collateral symptoms like
weight loss or night sweat, tumors should be in focus. Tumors located in
nasopharynx may cause problems with smelling and weight loss.
I suggest you to first have a check by ENP Doctor. A smelling test for objectivity should be done. In case of an Infection you may take antibiotics (
Amoxicillin 750 mg 1-1-1) combined with decongestant nose drops (Otriven 2/d)
In case of
chronic sinusitis with polyposis you should take
cortisone spray for more than 1 month and p.o. 20mg for at least 1 week.
If your problems persist you should do a CT-Scan of your face skull for further diagnosis. It would be good to exclude point 3 as well.
Please let me know if you have further questions.
Wish you good health.
