It sounds like y have a water infection.Dont know about y legs
have been getting cold legs for over 10 weeks now my stomache keeps swelling up and i must urinate 20 times a day i have a feeling that some one is pressing on my bladder had blood done all came back normal. i do have a small stomach ulcer which i take meds for . ulcer has never made my stomach swell like this befor
I suggest if you don't have an infection to see an endocrinologist so they can check your thyroid and such.Hope you can warm up, being cold is not fun.
