So two days ago my upper thigh just below my butt has started feeling prickly and uncomfortable when I sit on it. It feels like I've sat on a load of wood splinters. It is not very comfortable when sitting down but gets more tolerable as time goes on but the prickles are still there. I have no idea what could cause this but am suspicious of possible chafing because I came back from camping two days ago where I went swimming in the sea constantly and therefore wore my tankini all day every day. Has anyone got any ideas because I've tried various creams, ice, waiting etc... and it is still continuing. Thank you for any replies x
