Hi I, leaned in my van two days ago and scrapped very slightly my shin, just felt like you run your nail on your arm slightly, so didn t hurt and didn t think nothing of it, about 3 secs later, my shin was stinging like I got stung by some thing, looked down and the vein stuck up so big and was really think half way down my shin and really hurt I was trying to massage it, and it stated to calm down after about 5mins, but could point my toes or anything or touch it as it really hurt, not the pain is gone and I noticed today a really bad bruise half way down my shin, and thick around around my shin, is this normal, is there anything to worry about?
