Welcome to HCM.
Itching sensation without significant vaginal discharge
need not worry you. Tingling sensation
in the feet could be due pressing of a nerve
while you are sitting for a long time.
Itching in the vaginal region could be caused by fungal infection
of the skin. If you find discolouration of the groin and vulval region, then you need to consult your gynecologist, who will prescribe antifungal ointment for local application. Please do not take oral medicine for this, since it may have adverse effect on the baby inside your womb.
