I have developed a sore right buttock and have no idea what is causing it. A few days ago it was my left buttock! I know there is something which can affect your pelvis called SPD (or is that PSD?) but I don't think it is anything like that, but I have no idea what it is. I have assumed it is posture-related causing bottom strain but am just guessing really. Does anybody have any idea what it is and whether it is something I can prevent?
Thanks in advance for any responses!
