This sounds like a strange link I am making. Potted summary: Im 41 and suffered for years with undiagnosed endo. It all culminated when I had my ovary removed just over a year ago. About this time I developed a lump on my forehead and my GP said if it didn't bother me just leave it. This lump has got bigger and changed shape and a few weeks ago i revisited my GP and with a little persistence (she thought it was a cyst not bothering me)I persuaded my GP to refer me straight away for a scan. I've been today and it's not a cyst. I therefore think it is changes to the skulls bone structure. I've googled this and there's a link made with premature ovarian dysfunction ??? I am interested if anyone has developed any lumpy bits around the skull area. Please let me know I know it sounds a little off the wall!!
