My son has recently had 2 MRI's of cervical and lumbar spine. We know he has 3 bulging disc in lumbar region and 2 in cervical. The inflammation is severe, doctors have been giving him caudel blocks, but cannot find herniated disc. a few days after the first round of lumbar injections, he lost bladder control, lost balance and fell several times. No-one has been able to find the cause of these issues. There must be an underlying cause. MS was suggested but brain scan came back clear. Please give me some idea where to turn next. He is only 22. what else could it be if not spinal related injury?
