I had chronic shin splints in my 20s from doing high-impact aerobics. I don't think I've ever really had them since I gave that up quite a few years ago! I have gotten sore muscles on front of my shins from walking/hiking hills after being in flat areas, but I can't recall having shin splints. Seems like I remember reading that a lot of shin splints are caused by micro-stress fractures in the shin bones themselves. You can press right on the bone and feel the pain in a very small area in that case. Sure hope that's not your problem, Catrin, as only rest and not doing the activity will cure those. I'm pretty sure that's what I had back in those days thirty years ago. They hurt like H*LL!
