I don't know if you've experienced these kinds of headaches but it's the worst headache I've ever had -- it's 100X worse than the morning after way too much cheap tequila - really REALLY BAD -[/QUOTE]

Yes, I had those headaches after my first surgery in 2010. That is something hard to describe, one needs to have those to understand how bad that can be. I couldn't lift, the pain on the back of the neck was killing me. The headache would go away after I lied down. So I stayed in bed for 3 days and it went away but the leak didn't stop. We realized that much later. I was having all kinds of sensations in my head (ringing, pressure in my temples, in my ears).
Now, after the second surgery (to fix the leak), I never had those headaches but I have ringing... which might be a sign of a leak. I don't want to have an MRI right away. What for? Another surgery? I will have MRI done in 3-4 months and then will go from there...
It's been 15 days after the surgery. I'm going back to work next week.
