Hi, Thanks for the query. I understand your concern. The Ct scan report is suggestive of mild inflammation of maxillary & frontal sinuses.. suggesting sinusitis. Head ache,is sign of frontal sinusitis while sleep apnea can be due to sinus problem. Tingling follows swelling of sinus es .. causing irritation of local nerve fibers causing tingling sensation. To get relief.. you should get expert advise from ENT specialist along with self care - - drinking lot of water/ foment face & forehead with moist hot towel/ inhale hot vapor / avoid blowing nose strongly. * continue this for a long time after finishing the expert advised treatment... this would help keeping the sinuses clear & avoid recurrance. Thanks.
