Hi so I m a singer, strong belter singer and I ve been trained to sing from the right places, and how to breathe etc I m also a vocal tutor, so I m sure I m singing correctly, cause I can feel it. so the reason I m coming here is because I cant figure out why I m having a stabbing pain in my chest on the right side whenever I belt. I do have costochondritis, but that s mainly on my left side, but i don t feel the pain from there when I sing, I only feel I on my left side. I ve had to take tablets before I sing to numb the pain, but I know it wont solve the problem, so I m looking for a cause and solution if possible.
