A bottle of Castor oil costs around $3.00 and lasts for months. Simply rub and massage the oil into the affected areas at bedtime, then wear socks to bed. It may take up tp two weeks, but relief will come. The oil absorbs into the skin and the only side effect I know of is super soft skin, including rough heels. It has even relieved bunion pain, blisters, etc. I also rub it into sore knees, and it ruly helps. Not a wonder drug, so takes a little time. Use it religously and you will be pleased.View Thread
