I’m with you, I think we may have been in the same bar fight!
I try to be careful, but I never realized how much I bump my arms before the bruising started. The skin on my arms is going through some weird transition. It’s become crepey and so dry. I use lotions, sunscreens and drink plenty of water, healing creams, protective sleeves, etc. Nothing seems to make a permanent difference. Recently I (again) started using a powder calcium supplement to see if it might help. I go in cycles with some supplements, I take them a while then give my body a break. I know as I age calcium is deficient. I’m doing what I can from the inside out!
