Hey everyone so about a month ago I went to the gym early morning which I never do. I was doing bench incline and felt the back of my neck get so stiff that I wasn't able to move it up or down as good . We are in May now and my symptoms are left arm ache, little shortness of breath, neck pain, random shooting chest pain.. I'm only 23 years old and I did get my heart checked and everything came back positive for that. Anyone ever suffered from these symptoms and what would you guys recommend ? Thank you -Bernie
