Kate - good to hear that all those tests came back fine, hopefully it was a one-off thing. Although would still be nice to know what has caused it. I don't know everything about RLT, although it would surprise me if this contributed to your swelling. My OB has no problems with me taking doing the RLT thing - in fact last time he suggested it, so I kind of take that to mean that he sees no potential issues with it (perhaps combined with a dose of medical scepticism about it's efficacy )
