Not so good. What went wrong?
Just some self-inflicted suffering. Foolishly decided to go paintballing in the lovely September sun (errr...) this weekend, whilst already quite unwell. We won, but my Monday makes me question whether or not it was really worth it... 
Oh dear. Ive heard its painful. Do you ache all over?
I ache, yes, but from being out of shape and running around for eight hours, not from being hit. Unless you take a hit from only a couple of metres away, or in a delicate spot (I got one to the neck, which managed to get between the clothes and face mask, and my brother got one...somewhere tender), then it will only really sting for a minute or so. It will leave a mark, but I can prod at them and they don't really hurt. It's great fun when the opposition actually understand the rules, but both times I've been there were some non-English speaking players on the other team that didn't get that when you get hit, you're out. Was quite frustrating to shoot a guy three times and just have him turn round and fire back...

Give it a try though, if you're interested. Makes for a great day out, but it's definitely better when the weather has been good for a few days, for obvious reasons.
