What Causes Chronic Headache?

Hi,



My name is Vikrant Sharma . I am suffering with headache(at the back of my head) problem from last couple of years. It started when i was very thin. In aspiration of good health i joined gym and lifted so much of weight without guidance of a trainer. I stretched my chest and shoulder muscles as much as i could have. While exercising i used to feel pain and irritation but i completely avoid it. I tried different suppliments such as body plus powder, endura mass after which i felt more irritation than before so i have to left exercising.



Now I feel irritation throughout the day and night, as I put my head on something for example on pillow, on wall I start to feel uneasy. I feel headache when I talk on mobile, when I run or lift some weight. I feel like pumping inside.



Now i am left with less stamina and poor health so want to work on it but whenever i start working out some pressure on mind and irritation does not allow me to go further. I can not go for running and not even for walking.



I have gone for MRI of Brain and Survical tests. all are normal. I am also suffering from chronic sinusitis from last 10 years which may be a cause behind it or it may be some muscles imbalance due to wrong exercise. Please suggest me
