I Had A Blood Patch To Help With Spinal Headaches

I had a blood patch to help with spinal headaches after a spinal tap, this was two days ago. The headache relief was almost instant. The day of a had back pain, hurt to walk but it was so much better than the headache. As of today if i stand too long of move a certain way, turn my head to look behind me i get very dizzy, numbness in my arms and chest..my ears ring and i have to strain to talk, I feel like i could blackout...is this a normal side affect?
