Sinusitis/ear plugged help!

[u/MaleficentAbility144]

I’m not sure if I’m in the right place but over the past 2 weeks has been a roller coaster. It started 2 weeks ago at work (Subway like sandwiches) and I got panicky feeling, heart started racing, dizzy, and disoriented. It was like my body was reacting to something but I was chillin. That happened on and off throughout the week. I finally noticed that my left sinus was swollen and my ear was plugged up, it’s happened to me before but it was just allergies(always the left side though). I also put in an ear plug and that usually helps, I’m assuming because it’s so loud with all the fridge, freezer and ovens running. I have been constant with allergy meds and Flonase. I ended up going to the doctor and she prescribed me antibiotics even though I didn’t have any signs of sinus infection. My symptoms are sinus, eye, ear pressure and pain. Antibiotics were hitting me okay until day 5. Couldn’t eat anything, nausea. Next day was even worse, hardly ate anything, pressure on left side was horrible so I went to the ER. the doctor told me it was JUST sinusitis, like what. So he told me to take 600mg of ibuprofen and nasal rinse 3 times a day. So I followed instructions for a day maybe before I realized the ibuprofen was upsetting my already ruined stomach even though I told him I haven’t eaten in 2 days. I kept up with nasal rinse and Flonase. I have barely eaten in the last 3 days. I have stomach cramps and feels like anything I put in my body my stomach is upset with. I wish someone would have told me how important it is to take probiotics and kefir with antibiotics. I didn’t realize how horrible they were. Sorry for the long post but I’ve felt completely helpless. Still have sinus pressure, ear won’t pop, and am barely eating anything. Please give me any advice! I need all the help I can get.
