I've had sinus & ear issues for last 13 months. I've been under care of ENT & Allergy specialist. ENT did CAT & MRI of head and determined no issues. The Allergy Astema specialist treated me for 6 months & cleared up sinus infections after 6 rounds of antibiotics. SYMPTONS: Numbness & tingling of scalp & neck. Swelling & pressure beneath ears. Ringing in ears. Sinus drainage with blood that dries & blocks drainage. Scalp is hot to touch but thermometer does not register fever. With changes in sinus pressure vision blurrs. These were symptoms before & after treatment & no diagnoses has been given at present. Last appointment with Allergy specialist he determined symptoms not realted to allergy's & no infection at present. Referral back to ENT Specalist this month.
