did a blood patch today on a healthy female s/p a svd with and epidural a couple of weeks ago. She had a persistant postural ha that fit pretty good with pdph and she had tried conservative measures. She wanted a blood patch so we did it with 20 cc, she got immediate relief. But she had pretty significant lower back pain - worse on the right side. After an hour she could stand sort of ,but her back hurt when she put weight on the right leg. Pain did not appear radicular and No weakness, incontinence etc, would you guys be worried/what do you do next?
