Suggest Treatment For Burning Sensation On Cheeks

Hi Long story short... 37 yr old female...smoker...tea total...no other illnesses For 10 weeks my cheeks have been burning hot - mainly in the afternoons - they are not red though. Sometimes i have a low grade fever of about 37.1 sometimes i don t I have a tooth where the root lies in the sinus cavity and as i had toothache and earache my doctor thought the root was aggravating the sinus cavity so gave me antibiotics in case it was infected I ended up having 6 courses of antibiotics which got rid of the earache but not the burning cheeks I have fluid running down my throat all the time - assumed from sinus - and my tongue has a horrid yellow coating on it Some days i feel so awful as well as feeling swimmy in my head I now have a steroid nasal spray but dont think its helping Hot shower every day to steam sinuses which sometimes seems to stop me getting hot but could be coincidence I sometimes get itchy bumps on my face and left ear when the cheeks heat up Had bloods done and the only thing of note was potassium level raised at 5.6 Neck aches regularly and sometimes headaches but no facial pain so not sure if my sinuses are to blame Some days i feel like some of my muscles are a bit twitchy too and i have the urge to tense them Have been referred to hospital to have tooth removed as it is broken - got to have op as it is invading the sinus cavity and has a bent root which they are afriad may snap off and wander off into sinus cavity Don t want to suffer for weeks or months until this is done Today my left cheek (same side as dodgy tooth) is absolutely on fire and I feel shaky and horrible. The tooth is not hurting though Driving me potty - any suggestions?
