I've had a cold for several weeks and currently have lost my smell and taste. Amoxyicillin and neti pot didn't help. Any suggestions?

Loss of smell/taste. The sense of smell and taste can be lost temporarily due to colds as they can destroy your smell and taste receptors. The loss of smell can also be due to nasal/sinus congestion. They usually return after several days to several weeks. As you get older, the ability to smell and taste will decrease also. You should discuss your concern with your doctor.
LOST OF SMELL/TASTE. Colds, upper respiratory infections, sinusitis all can cause loss of smell & taste. In addition, many medications can cause loss of smell & taste. Amoxicillin doesn't help colds! check with your doctor . . . Again. Be patient . . . You smell & taste will come back.
