I'll speak from experience on this one. 5X's broke metacarpal in left hand, 3X's surgery right hand = long layoff. Made my pro debut in 2000, had hand problems during training for my next fight and almost 5 years later I'm just starting to train for my next fight. Wait until your hands are not hurting any more, wrap your hands good, get a pair of 14/16 oz. bag gloves. If u ever have a chance to hit a foam/water or water bag then do so. LISTEN TO YOUR HANDS, if they are hurt give them time to heal.
