I never used to get it either, I have had it since I had my little boy but some times I have it worse than others, I think I need a trip to the doctors as well and see what they say. Thank you for your comment x

I have this problem too. But I got it after childbirth. I don't think that it normal, any way - not such pain. I'm going to visit my doctor to discuss it.
I tried to find some information about it. Now I know, that a lot of women got this problem after childbirth too.
