If the day after your sports/deep tissue massage you wake up and your muscles feel a little sore, and some seem a bit swollen – almost like they’re bruised – or you feel completely wiped out and tired, don’t worry it is perfectly normal for your body to feel a little sore and out-of-whack the day after a massage (as counter-intuitive as it seems.)
For your muscles, getting a deep tissue massage is similar to experiencing a tough workout. The fascia (lining) of our muscles is supposed to be smooth, and work fluidly, however when muscles gets tight, strained or kinked, it becomes more rigid, and will rely on surrounding muscle areas to pitch in and help.
During a session, the massage techniques works to stretch, lengthen, and break up groups of muscles (commonly known as knots), possibly causing tiny micro-tears in the muscle along the way. This is a normal function of massage and, while it leads to more blood flow that area, it can also lead to that day-after tenderness. Also, if you happen to be dehydrated on the day of your massage, your muscle tissue will not be as pliable, and you will feel more soreness afterwards.
