Congestion

Hello everyone so I have had the craziest nights for about 4 weeks now I wake up around 3 and sneeze about 15-20 times and then I end up congested all day at night I am okay from one nostril but one is congested I thought it was allergies but zertec didn’t help thought I was catching a cold but Tylenol cold didn’t help neither does sudafed or musinex my doctor gave me amoxicillin and that didn’t help either either I am desperate to get my sleep back anyone else had this?
