Thank you for posting your query.
There is a possibility of dural tear while doing the ESI (epidural injection), which leads to leakage of cerebrospinal fluid
(CSF). This in turn leads to low pressure headache. Most likely, you are suffering from this condition. Typically, this headache is worse on sitting or standing and is less severe on lying down. It is a self-limiting condition and subsides in a week or so. Adequate hydration (drinking plenty of fluids and juices) are helpful.
There is no need to worry at present.
Please get back if you require any additional information.
