Hi
I started getting blood spots 3 yrz ago on my arms and shins. Blood work is normal. I don't have to bump them the stuff just appears. Was told it's called benign pupura. Mostly from thinning skin and beta blocker medications. I use a vit c oil with retinol or pure coconut oil it seems to work best to get rid of them. It is very discerning and bothersome but I guess just have to live with it. I did purchase forearm protectors off Amazon and they work well if your doing packing boxes or cleaning I wear them. I feel your pain
