Lidocaine 2% (preservative-free, without vasoconstrictor)Lidocaine 2% + Magnesium Sulfate 10% (combination)
What this trial is about
Two groups of patients diagnosed with Myofascial Pain Dysfunction Syndrome (MPDS) will be included in this study. One group will receive trigger point injections of lidocaine alone. The other group will receive trigger point injections of lidocaine combined with magnesium sulfate. The study aims to compare the effectiveness of both treatments in reducing pain and improving muscle function. Patients will be assessed using a pain scale (VAS) and surface electromyography (sEMG) to measure muscle activity.
