Comparing Efficacy of Dry Needling Combined with Passive Stretching and Muscle Energy Technique on Myofascial Trigger Points

The goal of this clinical trial is to assess and compare the efficacy of dry needling (minimally invasive treatment by using a tiny needle) combined with two types of stretching techniques in patients with neck pain for more than 3 months. The main questions it aims to answer are: Which combination of treatment will 1.give faster relief of pain? 2.improve neck range of motion? and 3.improve disability level of a person with neck pain. Participants who are interested will be selected according to eligibility criteria. Participants will be divided into two groups. Initially researcher will assess and interview the participants. Two groups will receive two different combinations of interventions. Pre and post measurements will be obtained and then treatment efficacy will be assessed.
