I suffered a severe headache about 3 yrs ago after going to gym. Next day could not sit up due to sever pressure running up spine into head. Felt like my head was going to explode & my neck was in severe pain. Could not sit up without screaming from pain rising up spine into neck & head for a couple of months. More than a year could not bear the pain & weakness suffered in spine shooting into neck, shoulders & head. Battled to keep my head up. Even schedule 7 drugs barely dampened the pain. I kept on wanting to collapse and pass out from the severe pressure & diziness into head, especially after sitting when I got up it would shoot up spine into neck & head. I even had hearing disorder for a few days. Now 3 years later still suffering, on & off it flares up and I cannot exercise, carry heavy objects or I'm in pain afterwards in top of back, shoulders, neck & head. Sitting for periods & getting up causes pain to rise from my lower back upwards. Iron level remains low too. Nobody knows what it is. Can't afford an MRI & have not been able to see a Neurologist. What do I do?
