This happened to me today. I went to get blood drawn, it hurt really bad. Later in the day, suddenly my old injury in my left foot, which originally started my RSD, started killing me with pain, then a little later, a surgery i had to remove a calcified mass from my butt, joined the foot pain & hours & hours later, the pain won't stop. Now normally I would attribute this to rain coming, but there isn't any rain in sight for days. Has anyone else had a similar experience?
