I do not have a rash or any signs of stress on the skin but I suffer at certain times from an excrutiating itch to the sole/s of my feet. This drives me almost insane as I want to stratch like mad. I am diabetic.
As a diabetic, is your blood sugar level well controlled?
Are you complying with lifestyle and diet modifications?
I suggest that you take extra care of your feet. Is the skin of the foot dry? Is there any visible abrasion, wound, rash or discolorations in the area ? Use a mild and light cream over the area to moisturize it. Inspect the area if there are any cuts or bruising. If there are any open wounds, a prompt consult with a physician is necessary and in cases like this do not apply anything on the foot.
For intact and healthy skin, moisturize the skin with Vitamin E and other mild and unscented moisturizing creams that may be available OTC. You may ask your physician for any medications which will help alleviate the itchiness (eg antihistamines).
