I've been going to the doctor's on and off for almost 2 years with various manifestations of this, even changed surgeries over it, and nothing conclusive has been found, nothing to help either. Just losing the ability to cope at present.
Physical symptoms: about 1-1.5 years ago they were regularly like early pregnancy every month. I took pregnancy tests - was not on hormonal contraception so could have been possible. But all negative. Then the symptoms have developed. I am practically moulting in terms of losing hair, but growing it astoundingly quickly everywhere else. Been going on a while. I have a very dry throat, a bit like hayfever, as part of period symptoms, and lymph glands behind the ears come up rather painfully, also making the jaw sore. I get dizziness and palpitations when standing up and when going outside for the first time in the day. If there is too long a gap between eating, I swell up so that I look like I'm pregnant. Really. And feel very bad, sick and shaky all night. Neither DH or I sleep very much due to toddler conditioning - so even when I get chance, I am regularly lying awake.
Mental symptoms: off the scale for about 2 days before, and the early part of, the period. Utter rage and despair but try very hard to suppress it. The rest of the time passes in a 'what the hell, can't be arsed to get het up about anything much' sort of blur, and I tend to react to everything roughly the same. But in this short window I have nearly left my DH twice and last night did tell him I would do so, at about 2 in the morning. So all hell is let loose there as we are trying to untangle the aftermath of that. I truly don't know whether it would be for the best or not. But the point is it was out of the blue for him, it has knocked him sideways, and given another week that would never have come to that. Periods themselves are grim and can last literally about 2 weeks. Gone on a pill that allegedly should stop them but it has not seemed to change a thing.
Strange pain under the right rib cage that seems to be present every day but not all the time. Pretty sure this is ovary, not gall bladder, but a scan showed all organs in great shape, and blood tests were normal (thyroid etc). I got tested & blood tested for ovarian cancer (things seemed to fit) and know I haven't got that but the scan revealed a normal, not particularly big or dangerous ovarian cyst. So what on earth is this? Is it really pmt? Depression masked by a massive slice of denial? I feel as if I am going crazy or am fantasising about symptoms which seem to me to be limiting everything and taking 'me' away but don't have an obvious physical cause. Just don't know.
