Brother I can relate, I started in 2018 with what I thought was a pimple on the right side of my neck under my ear.. it was the infamous Skin Cancer. Next comes my left chest, after that my nose, then my shoulder! Say what you will about the DC VA but dermotology there has been on target with me, They.ve burned off several spots on my head, chest, arms, legs and neck. The only place it hasn't come out yet... well hell I don't even want to think about that.
Stay strong, under cover and get the spots checked even if they don't look like cancer.
