Any alternatives to Vallium to relax muscles after breast augmentation?

Thank you for your question and congratulations on your breast augmentation.  During the immediate recovery phase it is unlikely that you will develop a dependency on the Valium as you have a medical reason to require its use.  That said if you would prefer a specific muscle relaxant you can discuss this with your surgeon as there are a number available on the market - robaxin, skelaxin, flexeril, etc.  Hope this helps. 

for muscle spasms but if you want to avoid more pharmaceuticals, you can try pulling your shoulders back to stretch the chest muscles when feeling the spasm.  

you are experiencing normal post op pain which can be relieved with Norco. I would recommend speaking to your plastic surgeon. You want to relieve the pain entirely and not let it build up until it is unmanageable.
