Myofascial pain syndrome is a condition that causes long-term pain. It can occur when trigger points (tight fibers) form in muscles and the thin layer of tissue that holds muscles in place, which is called fascia.
Myofascial pain can be felt whenever a trigger point occurs, but is common in the shoulder, back, face, and head. Muscle injuries and stress can lead to myofascial pain syndrome, although the exact cause is unknown.
Symptoms include:
- Muscle pain that doesn't go away
- Deep, aching muscle pain
- Tiredness
- General feeling of being unwell
- Tender spot in a muscle
