Joint issues may be a matter of inflammation, which can be quite serious. Rheumatoid arthritis is an inflammatory disease and it is degenerative. Most people who have arthritis, have osteoarthritis which is caused by injury or damage to one's joints. Arthritis can cause tendinitis.
The pain of tendinitis can be significant and worsens if damage progresses because of continued use of the joint. Most damage heals in about two to four weeks, but chronic tendinitis can take more than six weeks, often because the sufferer doesn't give the tendon time to heal.
For many people, the older we get the longer it takes to heal. Maybe it is time for you to take a vacation from working out. Trust me, you won't die or lose all your muscle if you do and when you're healed, you'll be ready to regain all that you lost and more.
I fixed my biceps distal tendon pain with 100 reps everyday routine (thankful to tacotrescombo on that!!!)
Maybe high rep dumb.front raise and bentover laterals would do a similiar trick, no?
I’ve had my share of soft-tissue injuries from exercising, but this was the worst. One by one, I had
to drop exercises until all I could do for back were pullovers and extremely strict DB rows.
I went through PT, which didn’t do much in the short-term, but I kept at the baby-weight (2.5-lb curls)
eccentric movements. It took a year to fully resolve, so dude, take Prime’s advice and take a break
before you develop something chronic. Time is on your side, so use it.
