I had a lower back/waist muscular spasm earlier. I don't think I have ever had one of those before; rather painful, a bit like a cramp. Now, that area is sore and stiff and I am having to be careful with how I move my body and what posture I am in. I suppose my body is telling me that I have been doing too much exercise targetting that area the last few days! I have been doing a lot of 'waist' exercises, admittedly, but that's because I enjoy them. Oh well, I am just going to have to wait until it feels okay before I do anymore RFA as I couldn't do anything in it with how it is right now. A lazy day today with perhaps a gentle walk and a hot bath before bed and fingers crossed a good night's sleep sorts it out. After lecturing people ITT about doing too much it is probably no more than I deserve. Physician heal thyself!
