Headache is a very infrequent complication of myelogram. Rest and increased fluid intake relieve headache in most cases. However sometimes blood patch may be required. In your case even blood patch has not relieved the spinal headache. I would suggest you to discuss this with your treating doctor as you may need a repeat blood patch. In many cases repeat blood patch is successful in curing the headache.
Hope this helps!
