Question: Hello my symptoms are:

Sinus pain
Thick yellow brown mucus cough up some or blow out
TMJ
Awful since of ear pressure and fullness muffled hearing like under water
Sinus pressure
Post nasal drip
Constant drip into chest/ stomach
Bad stomach pain and cramps watery stool thinking due to antibiotics
Stuffy nose and head
Watery and itchy eyes
Very fatigued and tired
Left eye spasm pressure more than right side
Cough

Allergic to codine and sulfa drugs

Lasted 3 and a half weeks
Temperature changes make symptoms worse

Took Augmentin 875 for 5-6 days had to stop due to very bad stomach issues went off a day ago

Have tried Musinex, sudafed, Allegra, nasacort, ginger oil and oregano oil drops, etc. prednisone I did several days but side effects aren't worth it with stomach and tmj aggravated and facial flushing and no sleep

So sinus infection/pressure pain/issues/congestion
Tmj
Stomach discomfort


Very frustrating it's been 3 and a half weeks

What do you recommend I take or don't take to catch a break and get me on road to healing? I have seasonal allergies and it all started with virus I guess 3 and a half weeks ago with sore throat that lasted about three weeks. My son had some of the same symptoms but he is better and seems to be feeling good unlike me who remains frustrated and fatigued.
Also is it normal to have pain behind the eyes especially in the left with spasm feel or should I be concerned? thanks for your help!
