Last night I went to sleep with a really tight shirt on (it was very tight around the arms especially) When I woke up my arms hurt so I pulled up my sleaves and my arms had a whole bunch of redish/pink lines on it going all the way down my arms. One arm stopped hurting but the one with more lines on it is still hurting right now and it's been sore all day. I can't write or clench my fist without it hurting. What happened and how can I get this to go away?
