You need to visit Jordan, Dead Sea and there you can get the ultimate benefit. For such deseases you cannot get well unless you spent some days there...

The cheapest option is The Dead Sea Spa Hotel (http://www.jordandeadsea.com/)
It is really good and you can use the fresh mud and swim in the sea.

My favorite is Marriott Hotel - Dead Sea. It is excellent and moderate in the prices.

If you are looking for a luxurious stay, choose Kempinski.
