Trigger points
Symptoms patients report
Ball of foot pain. Pain under first metatarsal head from trigger points near sesamoid bone region
Big toe pain. Aching in hallux from flexor hallucis brevis trigger point distal referral pattern
Pain when pushing off. Toe-off phase maximally loads compromised flexor hallucis brevis during propulsion
Sesamoid-like pain. Pain mimicking sesamoiditis from trigger points adjacent to medial and lateral sesamoids
Common causes
Running. Repetitive forefoot propulsion creates cumulative overload on hallux flexor mechanism
Dancing. Sustained releve and push-off positions maximally load flexor hallucis brevis muscle
High heels. Forced metatarsal head weight-bearing chronically overloads first ray flexor muscles
Overuse. Exceeding first ray muscle recovery capacity causes persistent trigger point activation
Poor footwear. Inadequate forefoot cushioning increases mechanical stress on ball-of-foot muscles
Treatment & self-care
immediate
Thumb pressure release under 1st MTP joint
Sit comfortably and place the affected foot on the opposite knee. Use your thumb to apply firm, sustained pressure directly under the first metatarsophalangeal (big toe) joint. Hold each tender spot for 20-30 seconds, then release slowly. Repeat on any additional tender areas you find across the ball of the foot. Apply enough pressure to feel a productive discomfort without sharp pain.
- Duration
- 3-5 minutes per foot
- Frequency
- 2-3 times per day
- Expect
- Reduced tenderness under the big toe joint and improved push-off comfort within 5-7 days
exercise
Big toe flexion and extension stretches
Sit with the foot flat on the floor. Manually pull your big toe upward into full extension, holding for 15 seconds. Then curl the big toe downward into full flexion, holding for 15 seconds. Repeat this cycle 10 times. You can also perform this stretch by placing the toes against a wall with the foot at an angle to stretch the toe extensors and plantar flexors alternately.
- Duration
- 5 minutes per session
- Frequency
- Twice daily, morning and evening
- Expect
- Improved big toe range of motion and less stiffness during walking within 1-2 weeks
exercise
Towel curl exercises for toe strengthening
Place a small towel flat on the floor and set your bare foot on top of it. Using only your toes, scrunch the towel toward you by curling all five toes. Spread the towel back out and repeat. Perform 3 sets of 10 scrunches. For added resistance, place a light book or water bottle on the far end of the towel.
- Duration
- 5 minutes per session
- Frequency
- Once daily
- Expect
- Stronger intrinsic foot muscles and better forefoot stability within 2-3 weeks
immediate
Sesamoid offloading pad placement
Purchase a felt or gel metatarsal pad designed for sesamoid offloading. Place the pad inside your shoe just behind the ball of the foot so that it sits proximal to (behind) the first metatarsal head. The pad should redistribute pressure away from the big toe joint. Ensure the pad does not bunch or shift during walking. Replace the pad when it loses its cushioning properties.
- Duration
- Wear during all weight-bearing activities
- Frequency
- Daily, throughout the day
- Expect
- Reduced pressure under the big toe joint and noticeable pain relief within 3-5 days
lifestyle
Transition to supportive, low-heeled footwear
Replace high heels and thin-soled shoes with footwear that has a low heel drop (less than 2 cm), a firm but cushioned sole, and a wide toe box. When selecting shoes, ensure there is adequate space for the big toe to move without compression. If dress shoes are required, choose styles with a platform or wedge that reduces forefoot loading compared to stilettos.
- Duration
- Ongoing
- Frequency
- Daily, for all regular activities
- Expect
- Significant reduction in ball-of-foot pain and prevention of trigger point reactivation within 1-2 weeks
professional
Podiatric evaluation for persistent 1st MTP pain
If pain under the big toe joint persists beyond 3-4 weeks of self-care, schedule an appointment with a podiatrist or sports medicine physician. The clinician can perform imaging to rule out sesamoiditis, sesamoid fracture, hallux rigidus, or gout. They may recommend custom orthotics, corticosteroid injection, or a specific rehabilitation protocol based on the findings.
- Duration
- One-time evaluation with possible follow-ups
- Frequency
- As needed, especially if pain persists beyond 4 weeks
- Expect
- Accurate diagnosis and targeted treatment plan that addresses the root cause of first MTP joint pain
- Pain under first metatarsal head from trigger points near sesamoid bone region
- Aching in hallux from flexor hallucis brevis trigger point distal referral pattern
- Toe-off phase maximally loads compromised flexor hallucis brevis during propulsion
- Pain mimicking sesamoiditis from trigger points adjacent to medial and lateral sesamoids
