Great question!
Let’s see: I had back and neck pain, sciatica in both legs, pain in both knees, muscles spasms that dropped me to the ground, shoulder, arm, and hand pain, gastritis, eye pain, but the one that scared me most was waking up to numb arms and hands.
That really scared me because all those other symptoms were restricting my level of daily activity as a husband and father of two toddlers, but the prospect of losing the ability to use my hands permanently was quite scary.
