Hi my name is Christine and I am new to this site. I have just had a caffeine infusion due to a low pressure headache. I had this done at The National in London . At first I was not sure if this was going to work for me but it has I know that this is not going to last fr ever and that it roves to my consultant that I have a tear in my lower back which is causing this problem. I have a spinal problem and have had 4 failed back operations, since that i have had on a regular basis epidural' s for pain relief together with morphine . Is there anyone else had this procedure and has it worked? I would be so leased to hear from anyone as I feel that I am on a- round- a bout unable to get off.
