Thank you for the information Cyclelops. I am glad to hear that your tum has improved and that you are doing better with that aspect of your illness, it all counts...

That is just great that these meds can cause movement disorders . I am a middle aged woman and I suffer from restless leg although i am not treated for it. At least that's what I think it is. Sometimes, I get jumps and rhythmic jerks from my lower body. I can't control it.

I don't think that it is related to the meds as I have had the rhythmic jerks for years (long before the GP). I have never been prescribed erythromycin - perhaps it is worth a try...
