I have Been unwell since I was 22 now 27. I have always had reactive hypoglycemia since young, also pcos. 
I'm exhausted weak ache in my arms which are heavy, lightheaded, leg cramps, hypotensive, intense brain fog and cold some days. Ears ringing tinnitus, joint pains,right eye peripheral vision shakes, cannot tollerate cold or hot weather, forget things... Low depressed.lost my life.... 
I have hydrocortisone which I tried but felt up and down on it and got leg cramps and anxiety. I've stopped it and now getting worse. Can someone help me get my life back, I have lost my friends and my relationship broke down, with a 3 year old and 1 year old this is hard. My mum and gran help me look after my children.

I no that my pituary isn't producing adequate ACTH but I'm sure my thyroid tests are not looking good and I do experience thyroid symptoms. i tried hydrocortizone but felt veru up and down,edgy not right at all.
