Cristal...go to ur Dr and have a cervical spine and brain MRI...u could have some trauma induced issues that were not addressed with the injuries since u did not have MRI's...which may I ask y not? especially if 2 were major injuries?
Please post an update after u find out what is going on
How are you? With your history of head injuries, it is best that you have this checked by your doctor or be referred to a neurologist for proper evaluation. Stronger prescription medications may help provide relief. Imaging studies are also important to rule out any organic issues. Take care and do keep us posted.
