Myofascial pain syndrome is when someone's muscles and the tissue surrounding them (called fascia) hurt a lot for a long time. It can happen anywhere in the body but is most common in the neck, shoulders, and back. It's like when you have a sore muscle after playing too hard or exercising, but it doesn't go away even after resting or taking a break.
Sometimes, tiny knots called trigger points form in the muscles, kind of like tiny balls that are squishy and painful if you poke them. These knots can make the muscles even more sore and cause some other problems, like headaches, trouble sleeping, or feeling tired all the time.
Doctors can use different ways to help treat myofascial pain syndrome, like giving you medicine, doing massages or stretches, or even giving you shots in the sore muscles. Staying active and doing exercises can also help to keep the muscles from getting even more sore. And if your muscles still hurt a lot, it's important to talk to your doctor about it so they can help you find ways to feel better.
