i had slight left jaw dull ache about 3 weeks ago, a little unusual. Last week, primarily in left side of my head, pain increased. Simultaneously, I felt sinus pressure with no symptoms of cold or allergy (no runny nose or drainage or sneezing). I feel like I want to pop my ears, as if my eustachian tubes are blocked. I have disk problems in neck C4, C5. I had been riding a bike more than I m used to and was wondering if slight neck strain from that. I have no history of headaches at all. I have more joint pain than normal. I am going to check for Lyme as I live in Albany, NY, a high risk area, although we are very diligent about ticks. I have been bitten a few times this year, but discovered them immediately before being too engorged. Took Doxy immediately. That was several months ago. These symptoms appeared in last few weeks. Went to doc. He doesn t want to images until a few more weeks, told me to take Tylenol and see if headaches decrease within the next few weeks. I have also had chest pain above the heart which I think could be gas or constipation or reflux. I am 61.
