Osteochondrosis is an incorrectly distributed load on the spine. Even when you relax during sleep, your body needs to be in the 'correct position' without bends, the spinal column aligned in a straight line. Using a pillow that doesn't conform to the curves of your body and fails to align the spinal column, relieving it from clamping, only exacerbates your condition.
Did you know that untreated osteochondrosis results in pinched nerve roots and arteries? Your brain experiences oxygen deprivation, hence why you sometimes wake up with a headache.
People live for decades with conditions like post-sleep headaches, neck, and back pain. The symptoms come and go, and individuals learn to live with them. However, in the end, it all leads to serious heart, vascular, and brain conditions. Such patients wonder, 'Why me?' without realizing that the accumulated ailment might be tied to years of issues with their spinal column.
What do people do? They often engage in long-term ignorance, only addressing the symptoms of headaches. Untreated issues can eventually lead to a direct consequence like ischemic stroke.
