Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 51
Healthy volunteers: no

Brief summary:
This study involves adult patients diagnosed with Myofascial Pain Syndromes (MPS). The purpose of this research study is to determine if there is a therapeutic difference between trigger point injection (TPI) of normal saline and conventional drug mix (local anesthesic + steroid) in treating MPS.

Detailed description:

Arms:
arm 1: Trigger point injection (TPI) with 1 mL of normal saline solution. Trigger point injection involves a single injection in the area of maximal tenderness or trigger point. This will be performed by the treating physician under sterile technique with a 25 gauge needle. arm 2: Trigger point injection (TPI) with 1 mL of conventional drug mix (lidocaine 1%; 10 mL+ triamcinolone acetonide 40 mg/mL). Trigger point injection involves a single injection in the area of maximal tenderness or trigger point. This will be performed by the treating physician under sterile technique with a 25 gauge needle.

Interventions: intervention 1: Normal Saline intervention 2: Lidocaine Hydrochloride intervention 3: Triamcinolone acetonide
