This does happen and the reasons can vary. It’s been a while since your last massage session and The massage you received was wasn’t light enough to accommodate the built up lactic acid causing soreness. Drinking A LOT of water after a massage is critical to flushing the lactic acid out so it doesn’t settle back in.If you don’t drink the water, chances are you’ll be sore the next day.In general, your body carries so much tension that the early sessions can be the most challenging to receive and therefore you f eel tender and sore after those initial sessions. More than likely, the more massages you receive the more supple your muscles become, in turn the less soreness you will feel post massage.
