For the last six months my health has deteriorated rapidly. One day at the end of October, I was walking home when my vision seemed to lose peripheral quality, all I saw was leaves and dizzyness brought me down to my knees resulting in a panic attack. I have a history of PTSD which of course contributes to my distress. I'm awaiting an appointment for an urgent CT scan due to headaches on waking and other symptoms. My GP is also querying Addisons disease which I have read a little about but other than that I am pretty naive. My symptoms consist of headaches, head pains, pains in joints, tenderness on scalp, stinging pain under nails (usually when asleep - it wakes me up), weakness in legs and arms, mild face pain, twitching of toes and fingers, dizzyness - drop to ground before i faint. I also have diagnoses of hypermobility syndrome, mild PAD, Asthma, hypothyroidism. I would be so grateful if someone would get back to me because I am so anxious and have convinced myself I am going to die. Also can a CT scan be done without the contrast and what can they give me to keep me calm if the Diazepam I already take is not adequate.
