A top professor in anatomy asked me today to describe how SPD really felt like to him. Oddly enough, despite so much experience, I was only able to waffle on for 20 minutes about the NHS and its shortcomings with regard to treatment. So I thought it might be good to crowd source and ask everyone on here with experience of SPD to describe their own pain/sensations, so I can pass them on (he will use the information to inform his lectures and give a human dimension).
