Interesting in the article Taz that it mentions a head injury. I get a 'strange' sensation on my left forehead - I fell over about 8/9 years ago, had both hands in my pocket and hit my head on the pavement. It resulted in a cut on my brow bone which fortunately was butterfly stitched, but left my eye and the entire left side of my face very swollen and bruised for several weeks. Whenever I mention the headaches, the doctor says it is a knock-on effect of the anxiety or could be result of nerve damage after that incident. To be honest, I have had so many weird headaches and pains since I was early 20 (now 48), that I think if it was anything serious, I would have been long gone. I also note the mention of sinusitis. I am also thinking that I notice the burning smell more when I have this head sensation - guess there could be a few explanations, but it only lasts a short time and if I put perfume or something on, I forget about it or don't notice it anyway. My husband is convinced that all my symptoms are because I worry - if I don't have anything to worry about, I worry. I was as bad as this in my 20's but after a few years, everything went back to normal and I lived a 'normal' life. This has all started happening over the past couple of years since I was diagnosed as perimenopausal, so I am assuming that it's all linked. Just hope I hurry up and metamorphosise into whatever I am 'changing' into - at least when that is all done and dusted, if the symptoms are still there, then I know I perhaps have some other underlying condition.
