absolutely! you always need to let your doctor know if you are not getting better. there can be many reasons a treatment doesn’t work. your doctor will make sure that the diagnosis is correct. sometimes a new problem has appeared that is complicating your condition. other tests such as labwork or xrays may be needed to see what is going on. then he or she will consider other treatment options. sometimes a different antibiotic is necessary or a longer course of therapy. the doctor may suggest other things you can be doing at home to make yourself feel better. here is more information about help for sinus pain and pressure. if you still are not getting any better ask for a referral to an ears nose and throat specialist.
