Thank you for all your advice, it was my GP and doctor who drained my cysts who said advisable to stop HRT as could be causing them as had a few trips to get them drained. I think will go back on HRT as like Dotty described it is heavy aching thighs, spasms/cramps that has been getting me down over the last few months, will be fine for weeks then hurt for a few days and go again on a cycle so sure it is due to low estrogen.
