I am sorry you are struggling post-op. I had decompression surgery in 10/04 and I know somewhat how you are feeling. The symptoms you describe definitely merit a quick call to your surgeon. I assume your doc opened the dura membrane during the surgery , which means you could have a leak in your CSF causing some issues. Amazingly, high CSF pressure(caused by blockages) and low CSF(caused by a leak) share some of the same symptoms. Does caffeine help your headaches? Caffeine stimulates production of CSF and can help with the awful explosive type headaches that accompany low CSF.

Just know that you are not alone and you need to trust your instincts and care for yourself as you would one of your patients: if you would advise a patient to call their dr, then you should call yours.
Stay positive ( I know its hard when you are in pain) and keep me posted.
