severe pain on right side of kneck ,felt like a sprain at first (approx 4 wks ) I ve had severe right shoulder pain that kinda goes up kneck with movement to right side reaching .It s progressively gotten worse w/in last 4 wks. It s not an ongoing pain but once its aggravated it is very painful for hours at a time. It feels like a Charlie horse x 3 . I m not on any prescribed meds , I exercise at least 3x a wk.,no medical history . I m stressed x 10 ,not resting properly bc of cheating spouse that is about to be history . It feels like a strain muscle or tense bc area is very tight .
