Sorry to hear about your chronic pain ER & others here as well.
Agree with posts...weather especially is an indicator for me. As far as the
...well I don't indulge but hey smoke em if you got em & bum em if you don't.
My left knee is spent, no medial meniscus since an instrustive reconstructive surgery (sports-related) in 1979, a couple of other scopes, now bone on bone contact, degenerative arthritis. I still stay active, go to the gym to ride a bike & elliptical & move it as much as I can. Keeping the strength up in the supporting muscles (quads & hamstrings) plus easy stretching helps a lot. Hell I even ski (no bumps), its not like I can hurt it anymore than it does...a couple runs & then hang out in the lodge works wonder for the spirit!
But...somedays it hurts bad & won't bend very well but on those days I try to focus on what I do have.... like ice & Ibprofren, Tylenol Arthritis or Aleve.... Insurance to go to the Orthopedic.... a gym membership, a good leg ... whatever it takes. I really try not to take even over the counter meds, but understand everyone's pain tolerance is different. Do what you have to.
Wish you the best in your situation for sure & hope you get relief soon!
