About 2 days ago I've been experiencing chest/throat pain if I sisterile it does not hurt at wall but if I breath heavy I do a lot also hurts a lot when I yawn or drink anything, I haven't been sick or anything for ages does anyone know what this might be, I have had no chance to go to the doctors becausI uh mother is constantly working and my mums partner works away 

 

thank you regards

Daniel
