I had a CT myelogram of the lumbar spine 3 weeks ago because I am still having pain after my lumbar spinal fusion a year ago. Since the myelogram I have had a very bad headache. I was told to lay flat or max of 30 degrees, drink lots of fluids, and drink coffee. I had done this for 2 weeks and they finally had me come in for a blood patch (first had to wait 5 days to stop Coumadin).
Now 7 days after the blood patch, I still have the headache. mostly when I'm up, but sometimes I wake up with it and I have a constant high-pitched buzzing noise in the right ear, which has now become bilateral. My thinking has become fuzzy too and my memory isn't good.
Is this dangerous for a CFS leak and the headache to go on so long? What's next after a blood patch?
