Hi Db99 I like you're name as I had an old friend that dB was my nickname back in my teens. But I'm not familiar with the other areas you have posted but this one of shoulder pain I delt with and even occasionally flairs up. Mine was mostly solved with some physical therapy. It's amazing what some properly taught stretching by a Physical Theripist can accomplish, i went thru therpy of about 10 weeks of 3 times a week a few years ago, my doctor referred me to one and the combination of Stretching, strength training and deep tissue massage repaired a bad rotator cuff area. Now its like new again.
So maybe talk with your doctor about getting referred to work on that shoulder. Good Luck and on the other areas I'm sure someone with those particular areas will join into the discussion. We are all just patients who have had and have medical issues and share our experiences to help others with similar issues. I myself am a Heart Transplant recipient but saw your post and wanted to at least help with the shoulder pain. Please if I can add anything ask away.
Blessings
