I've had 4 concussions, two that were very bad, one that resulted in amnesia & loss of time. After each injury I was diagnosed with PCS. Making things worse I'm bi-polar. My last injury was in 2002 & was the worst. I've had bad headaches since the first concussion but over the last year they have gotten progressively worse. Now they can last for days & cause nausea, vomiting, not to mention crying. At times the headache affects my entire head but there are times when it focuses only on the right side of my head from my eye back & the entire right side of my head would actually feel better if it would explode. Has anyone had this happen years after the last injury? I have no health insurance so doctors are limited. The pain is becoming unbearable. Any comments would be greatly appreciated as I'm growing increasingly worried & desperate. Thanks in advance.
