Should I get a CT scan for my unbearable headaches?

I am70 years male with diabetes and HT in control since 15 years. Last month I got cold and flue like infection with stuffed nose , back flow and sore throat. But I still have not recovered . First time I feel persistent mild headache in frontal sinuses area specially on left side and pain in forehead, itching , burning and tired eyes like symptom. Vision too was checked and numbers changed. I feel pain deep inside left nose around eye corner. That is my reissue. Both eye and ENT experts have cleared that nothing abnormal found. It may be allergy. But symptoms are not allergy. I took monte Lukas with levo cetrogen . I feel pain and stiff ness in my neck with spondylosis. Could it be that or some deep infection in left nostril What could line of diagnosis/treatment including x-ray of PNS and MRI of head and neck .Or is it due to some thing up in the nose?

I am 68 year old retired person. Over all my health is ok and vital organs are functioning satisfactorily. One problem I am facing since last two years is whenever I sleep left side I get pain in the left side of the head. If unknowingly I sleep for hours together the pain migrtaes to left ear or even to other parts in left side. So I need to take pain relieving medicines in such cases. Earlier such cases used to be at larger intervels but now a days it is frequent. It also happens that some times I getup witha head ache(leftside).My BP is under control and is under medication. One doctor suggested consultation with neurologist.But before going to specialist I would get the opinion of a General physician if there is any medicine you can suggest.

My nerves c4 to c7 are narrowing due to which I feel headache, neck pain and dizziness all the time. Pl advise me best treatment to heal this problem
