Wall Mart sells a generic heat cream, Equate Ultra Strength Pain Relief, it has camphor, menthol, and Methyl Salicylate. I use it when I have a muscle cramp at nite and it relaxes the muscle and relieves the cramp. I will also use it if I've overtrained and have a really sore muscle like biceps.
Bi's are such a small muscle your probably gave it all the training it needed first time out if you did pulling moves prior like pull downs, rows, etc. No reason you should be as sore as you are. It keeps you out of the gym waiting for them to heal or you will risk inj. and a rolled up bi will keep you out forever. Really crappy way to start your weight training endeavor. This is why I like DOGG CRAPP training so much. It tells you when your overtraining / undertraining and what to do if you are.
