I am having a lot of trouble finding a vein. All the veins in my arms, hands, feet, legs are gone. I have tried my neck and got it once but it is sketchy af. I have 31g 1ml 5/16” and 29g 1ml 1/2” rigs all brand new. I have been trying to find my femoral vein and can’t hit it I am also scared to dig around too much obviously. Please help me with hitting my femoral or anything to help me find a vein I can hit. I don’t even really have too many tracks on my arms but I can’t find a vein for the life of me. So I don’t know if they are all collapsed or what
