Hi, I have recently been diagnosed with GCA and am currently taking prednisolone. Started at 12 a day for two weeks, then 10, am now taking 8. Does anyone else get up at 4am?, get palpitations on waking and suffer from tinnitus with their heartbeat pounding in their ears? It's driving me mad. Also, my neck has started to swell. Is this normal? Some days my legs feel like jelly and my hands shake. On 12 a day, I was extremely hyper but that appears to be slowing down now. I also think I talk a lot more than I used to, and have started to say hello to people I don't even know!! I think I am going mad sometimes. Anyone out there that can put my mind at rest please?
