I have had itchy skin for the past 6 weeks, mostly in the inner thighs and beltline, its like an allergic reaction to something, I saw a doctor who suspected it was yeast overgrowth. Just in the past 3 days I have very swollen lymph nodes under my chin and my throat is sore as well as swollen gums and multiple canker sores on my togue, cheeks, and gums. I usually never get canker sores.
