The pelvic joint gives my a little bit of issues when I do cardio. They plated over the joint at the front of the pelvis, so it doesn't absorb the impact as well and causes some pain after running a while. A few years ago I could only run about 1/2 mile before it was hurting so bad I couldn't go anymore. Now I can do 3-4 miles before it starts bugging me.
My arm however, is a different story. I ended up with a lot of scar tissue there and it constantly a problem. Especially on heavier lifting like bench press. I think because the plate doesn't let the bone flex (to absorb the pressure) I feel the "bite" of the screws. Between that and all the scar tissue, bicep and tricep movements hurt as well. But, I keep plugging along... It's gotten a lot better over the years. The doc told me that I have scar tissue wrapped around the nerve that controls my thumb and index finger which causes them to go numb and/or shake from time to time. They tried to go back in and clean it out, but I still have the issue.
But, God is good. I could be in a box six feet under. And everything still works mostly. So, I'm thankful.
