Red bumps

I'm not sure what these red bumps are... It popped up just today this morning.  I played volleyball yesterday and slept for the rest of the day.  I didn't shower or anything because I was too tired.  While I showered in warm water this morning, I realized there are seven red bumps all on one thigh.  Four are in a diagonal row .  It wasn't itching at all until some hours later.  Soon I felt an itch on my upper arm and I scratched it a bit.  A little bit later, a red bump pops up at that same itching spot.  Now, another red bump pops up on one of my hands after it started itching.  These bumps aren't bigger than a penny by the way, but not that small either.  It's VERY noticeable... especially 7 of them on my left thigh..

I really, really want to get rid of these bumps asap, especially on my thighs since I play volleyball in shorts.  Do you have any idea what these red bumps could possibly be?  

Please, help.

If you have rash in a diagnoal row the bite cause may be bedbugs.Did you travel out?This  we call as Cimicosis,a bite reaction.Calamine external should do.The linear leisions makes one think thus.

I haven't been traveling, but I've had past bug bites because of ticks from my dog and my cat.
Could that possibly be it?  
So, if it's called a bite reaction, I got all these red bumps from one bite ?!

Sure do, the line of travel of bite decide

More bumps are popping up already on the second day!
Is this suppose to happen continuously until I get my treatment?
