CSF leaks must be pretty common. I also had the same after decompression. One month after my 1st surgery, my surgeon went back in to repair the leak. 6 weeks after the 2nd surgery I was in terrible pain with hydrocephalus and had shunt surgery. My cousin's daughter had the same 3 surgeries. I wish they would have simply put in the shunt rather than trying to repair the leak. Now, over a year after surgery I have a syrinx that I didn't have before, evidently a result of trauma from surgery...

I hope your leak resolved itself and that you didn't need any further surgery! I wish you well.
