I crushed my ribcage & sternum 20+ years ago & still live with pain in my shoulders and the vertebrae below my neck. When my day is running well(enough), the pain is present but barely registers in my consciousness. When non-physical tasks are a chore &/or I am depressed, they burn hotter than the sun. Physical activities seem to be the only remedy to abate it. I've found nothing beyond exercise relieves the pain when it's lit up: anti-inflams / pain killers don't do anything, chiropractors didn't help and imaging indicated no trauma to my spine. Perhaps it's some sort of arthritis or psychosomatic reminder, IDK, it's just another item on my 'getting old sucks' list.
