Hi Victoria,
I also suffer with pain and am medicated. I am so sorry you are going through such bad headaches. I understand about headaches with vision loss and severe "ice pick" pain. I also had an MRI that show a 3mm spot on my brain that is getting abnormal or no signals. I have yet to have the neurologist explain to me what this is. You can read in my signature about my injuries. I have had 8 concussions and have Post Concussive Syndrome.
I would be happy to talk to you. You are not alone. I know how it is with just needing to vent.
I am usually on the traumatic brain injury section. Feel free to send me a private message. I hope you are having a good day.
