Dear Chris,
I am going through exactly the same thing. I had a sphenoid sinus infection in September last year. After 3 months on antibiotics, many MRI's and CT's and blood tests, my headaches on the right side, I have had ongoing headaches, more like daily migraines. In the last 5 months I have suffered from throat tightness, chest tightness and pains, shortness of breath, dizziness, many sleepless nights, nausea, numbness in the face, legs, arms and lots more. I have seen 2 ENT specialists, 3 neurologists, a cardiologist, a naturopath, psychologist, physio and 3 different GP's. I have had a cardio echogram,2 ECG's chest x-ray, more blood tests, gastroscopy,and honestly I cannot remember what else. For the last 2 months my GP keeps on telling me that the tightness in the throat, which extends to the chest and then triggers the headaches is caused from anxiety. I don't particularly feel anxious about anything. I was very worried that I had a tumor for many months as it took forever to clear the sinus infection and am generally a person who runs around juggling 100 things at a time but can't come to accepting the tightness in the throat and all the other symptoms that come following are anxiety. Some days I get the tightness all day. Some days it presents itself as if someone is chocking me, sometimes it feels as if I have something stuck in my throat and sometimes a very uncomfortable restriction of some sort. I have been looking for an answer for the last 5 months. IF you come across one please let me know. What type of specialist are you seeing in August? For now I wish you the best of luck. Hang in there you are not alone.
Regards
Gina
