Hi
Welcome to the MedHelp forum!
Itching of feet could be due to anxiety, eczema, dermatitis, fungal infection, psoriasis, peripheral neuropathy or even due to skin stretching because of swelling. Usually conditions of heart, kidney, liver or low protein or severe anemia, which cause ankle and leg swelling cause both ankles and legs to swell. Hence if both ankles and legs are swelling then you will need to get heart function assessed by ECHO and EKG, get kidney and liver function tests done and get a complete blood picture for anemia. Low sodium in blood, hypothyroidism and malabsorption syndromes causing low protein in blood have to be looked into. Do discuss this with your doctor and get yourself examined.
Hope this helps. Please let me know if there is any thing else and do keep me posted. Take care!
I'd check into parasites, sounds similar to my story. They can live in your body and spread throughout it. Cause weight gain/loss/mood alerations/anxiety/rashes/swelling. Or it could be a thyroid problem or stress. I'd go to the doctor to get your blood taken to make sure your levels are where they should be for you're body.
