Ice helps to restrict blood flow to the tissue and decrease inflammation, while heat is better to promote blood flow and regeneration once the initial injury has healed after 48- 72 hours. Using heat initially will only promote inflammation. You will probably benefit more by allowing the muscle to rebuild itself before stressing it again. The muscle will regenerate stronger if given enough time, restressing to soon can result in injury and actually weakening of the muscle.
You can also use heat on it before you workout to help loosen up the muscles and then stretch it really good. I would ice it after your workout to help with the pain. Does your forearm hurt when you let's say twist open a lid like off of your protein jug?
