SCS and Psychological Readiness

Pain and the Mind Are Connected — What Brain Science Tells Us

This is not about willpower — it is about brain and nervous system science.

Chronic Pain Changes the Brain

When pain persists over a long period, the brain regions that process pain become hypersensitive. This is called central sensitization. It means that even small stimuli can be felt as intense pain.

Depression Changes How You Feel Pain

In a depressive state, the brain chemicals that naturally suppress pain (serotonin and noradrenaline) become less effective. As a result, the same pain signal is perceived as more intense.

"Catastrophizing" — A Pattern of Thinking About Pain

When you find yourself repeatedly thinking "This pain will never get better" or "Nothing I do will help," this is what medical professionals call pain catastrophizing.

This is not a character flaw. It is a pattern that the brain has learned as a result of living with pain for a long time.

Research shows that when this thinking pattern is strong, even if SCS reduces your pain, you may find it harder to feel the improvement.

Key point: Depression and catastrophizing do not weaken the actual effect of SCS. However, they affect whether you can "feel" the benefit of treatment. If identified early, steps can be taken to address them.
