Thank you for posting your query on DoctorSpring.com.
I have noted your symptoms and they are suggestive of post spinal (lumbar puncture) headache. It is fairly common and there are no other symptoms apart from the headache. The headache is caused by leakage of Cerebrospinal Fluid (CSF) from within the outer spinal membranes (the dura mater) and traction on pain-sensitive structures.
It subsides on own in most people but in some, it persists for long. In those patients, it is better to put a blood patch to seal the leak in the dura mater (covering of spinal cord and nerve, which gets torn due to the spinal tap). It is a minor and safe procedure, and the decision depends on the severity of headache.
I hope this helps. Feel free to discuss further.
