Following my last message. Removed the transdermal patch of Menorest. After 24 hours the pain eased. Consulted my gynacologist and she said that there is definitely a link to having problems with estrogen and progesterone and IBS, advising to stay off the products and try to get relief from hot flushes through Promensil and soya milk etc. Seeing naturopath this week and will report back on her comments.
