I have a herniated disc just had mri. pt said hyper reflexes, could disc be the cause and is hr dangerous as i googled it and it's scary.

N. root inflamation: Herniated discs may very well be the cause of hyperactive nerve reflexes. However it could be caused by other situations also, Like for example Rx medications, too much pop/caffeine, hyperthyroidism, electrolyte imbal, Serotonin Syndrome, Multiple Sclerosis, Rye Syndrome to name a few. The most common cause of "hyperrelexia" is spinal cord injury or inflamed nerves exiting the spinal column.
