Intense pain in my arm...

[TxRedMan]

this is a result of not lifting in years, and then exerting yourself too much in a short period of time.

you must crawl before you can walk.

it wont go away, you've got a ton of lactic acid built up in your muscles that will dissipate over the next week.

i reccomend stretching it in the mean time.

it will hurt like hell, but it's all you can do, really.

also, next time try and pace yourself.

lifting weights is a marathon, not a sprint.
