I was diagnosed with PCOS over 20 years ago.  1 year ago I am now type 2 diabetic.  Last few months my ESR levels have been over 80.  I have hot flashes on my face and a lot of join pain that wakes me up in the night sometimes.  I have had 2 bouts of kidney stones over the last 20 years.  I am in my early 40s.  My right foot has swollen twice the size with no injury and I have been on anti-inflamatory medication now for a month and a red rash originally thought of as viral, but has lasted 4 weeks, so GP not sure now.  Not hives.
Thanks for the questions I have found you have PCs, type 2 diabetes, with swollen foot also you had kidney stones. I would have also considered the possibility of gout simply because of kidney stones, you are diabetic then your kidney function might have been damaged for uric acid excretion.Also, PCs is generally found in slight overweight females. Also diet has big influence on uric acid. Get your serum uric acid checked am just considering another possibility, although I haven't examined anyway get well soon
