Thanks for using the forum. I am happy to address your questions, and my answer will be based on the information you provided here. Please make sure you recognize that this forum is for educational purposes only, and it does not substitute for a formal office visit with your doctor.
Without the ability to examine you and obtain a history, I can not tell you what the exact cause of your symptoms is. However I will try to provide you with some useful information.
As you mention, leakage of cerebrospinal fluid (the fluid that surrounds the brain and spine) leading to low
pressurePressure ulcer of
CSFCerebral spinal fluid (csf) collection
Csf cell count
Csf chemistry
Csf protein test
Csf total protein
Glucose test - csf can cause headaches, and the headaches related to this classically improve when the person lies down and gets worse when the person sits or stands. The leak is most often detected by a CT myelogram, though in some cases a CT myelogram may not show an abnormality. In such cases, presumptive treatment for a leak (with a procedure called blood patch) could still be done if there is a high suspicion of such a leak. In other cases, treatment of the headache with typical medications that would include caffiene, NSAIDs, and IV hydration will usually allow the headache to resolve and the leak to resolve spontaneously with time. Continued follow-up with your physicians is recommended, with referral to a headache specialist (a neurologist specialized in headache disorders) for management of your symptoms if they persist.
Thank you for this opportunity to answer your questions, I hope you find the information I have provided useful, good luck.
