I keep getting hot flashes as of now. My chest, throat, and head have burning sensations. I don't know if this Is heartburn or something else. I stopped taking the antibiotics and I'm worried that i'll develop resistant bacteria and it will lead to something deadly. My throat/head is on fire right now. I still feel like someone is stepping on my chest and I'm getting sharp pain under my left breast. I took tums to alleviate the burning in my chest but it's not working. I read something somewhere about sinus infections causing burning sensations in the head and they can also kill you?? I'm freaking out and I can't go back to the ER cuz I just got back this morning.

can stress cause this? I can't seem to calm down
