Hi Diana, thankyou so much for your response, your post is very reassuring to me. You are so right with your timing as mine are exactly the same. Can come for months and go for months, I used to think it was around period time but now I am not so sure I get confused as I think they all seem to run in together (ovulating and periods) will look into your medication, I have had heat packs on my calves every night for about 3 weeks and nothing seems to work, magnesium, panadol and codeine I have tried it all and nothing greatly settles them, thanks again, It was lovely to hear from you.
