Trigger Point Signs and Symptoms: Unlike, the deep aching pain associated with most myofascial triggers, Travell and Simons note, that triggers within the Palmaris longus elicit a prickling type pain involving the palm, base of the thumb, and distal forearm. Usually, predicating this atypical pain pattern is tenderness and soreness of the palm which makes it difficult to grasp and/or use hand tools. The pain experienced is easily confused with a cervical radiculopathy.

Trigger Point Activating and Perpetuating Factors: A direct trauma e.g. a fall on the hands, weeding or pruning, using a saw or hammer, or walking on crutches.

Differential Diagnosis: (Segmental, Subluxation, Somatic dysfunction) C7 C8 or T1 radiculopathy, Subacute meningitis or Peripheral neuropathy, Dupuytren’s contracture, Frostbite, Diabetic neuropathy, Polyneuropathy, Charcot’s arthropathy, Carpal tunnel Syndrome, Eosinophilic fasciitis, Raynaud’s Phenomena, Raynaud’s Disease, Complex regional pain syndrome (Reflex sympathetic Dystrophy), Fibromyalgia, Systemic lupus erythematosus, Osteoarthritis, Rheumatoid arthritis, Bursitis, Systemic infections or inflammation, Nutritional inadequacy, Metabolic imbalance, Toxicity, Side effects of medication.
