I have constant headaches 24/7.They very in degree, ranging from 3 - 9 on the pain scale, but they are always there. Also I m tired, have some weakness. At times I m disoriented and feel like I m a little drunk (loss of balance). Also, it may not be related, ringing in the ears, lately some ear pain and neck pain. Blood pressure is good and so are my eyes, had both of those checked.
