Many people feel that their arthritis pain is worse at night.
This is due to several possible reasons:
Anti-inflammatory hormones are lower at night.
Higher levels of melatonin and prolactin at night lead to pro-inflammatory cytokines.
Fewer distractions at night give you more time to think about the pain and discomfort of arthritis.
Lying in bed in one position for too long can lead to stiffness and pain in the joint.
