Myofascial Pain Syndrome

Overview

Myofascial pain syndrome (MPS) is a chronic muscular condition characterized by the presence of trigger points — hypersensitive knots within muscle tissue that produce local and referred pain when compressed or irritated. Unlike generalized muscle soreness, MPS pain is often persistent, reproducible, and may radiate to distant body regions in predictable patterns. It is one of the most common sources of musculoskeletal pain seen in outpatient settings.

Common Symptoms

•Deep, aching muscle pain that does not resolve with rest

•Palpable, tender "knots" within affected muscles

•Referred pain that travels from the trigger point to another area (e.g., upper trap pain felt in the head or arm)

•Restricted range of motion or muscle stiffness

•Sleep disturbance due to persistent discomfort

•Fatigue associated with ongoing, unresolved pain

Common Causes

•Acute muscle overuse or repetitive micro-trauma from work or sport

•Poor posture sustained over long periods (desk work, prolonged driving)

•Psychological stress, which increases baseline muscle tension

•Joint dysfunction or nerve irritation that creates secondary muscle guarding

•Prior injury with incomplete rehabilitation

•Nutritional deficiencies (particularly vitamin D, B12, and magnesium in some patients)

Who May Benefit from Treatment

Patients with chronic regional muscle pain — particularly those who have been told their imaging studies are "normal" yet continue to suffer — often find that MPS is the underlying diagnosis. Office workers, athletes, and patients recovering from other pain conditions who have developed secondary muscle tension are especially likely to benefit.

Treatment Options at Echo PMR

•Trigger point injections using local anesthetic to deactivate active trigger points and reduce referred pain

•Dry needling coordination as an adjunct to medical management

•Medication management including muscle relaxants and low-dose adjuvant analgesics

•Physical therapy referral emphasizing manual therapy, stretching, and postural correction

•Nerve blocks when concurrent nerve irritation sustains the myofascial cycle

•Ketamine infusion therapy for refractory cases where central sensitization has developed

Recovery Expectations

Many patients notice meaningful pain reduction after the first one to two trigger point injection sessions, though a series of treatments spaced two to four weeks apart typically produces the most durable results. Addressing contributing postural or movement factors through physical therapy is key to preventing recurrence. With a comprehensive approach, most patients achieve substantial long-term relief within two to three months.

When to Seek Care

If you have had persistent muscle pain, tender knots, or unexplained referred pain for more than four weeks — especially if imaging or prior treatments have not identified a clear cause — schedule an evaluation with Echo PMR. Untreated myofascial pain tends to worsen and expand over time.
