How do you feel doing rowing type motions? If that doesn't aggravate it, I'd say this is a perfect time to get in some excessive back work.. It's usually a good idea to get in more “pulling” (back) work than “pushing” (chest) work, and most people don't, so this could work to your advantage.If it does aggravate it, like Sammy said.. Just rest it.. Maybe try some wall pushups or something just to get some bloodflow into the area for healing purposes.. Try some epsom baths also.
