I suffer from RLS also cramp. I was told about the bar of soap, so I duly placed one under my sheet, and I can honestly say I have experienced great relief , and a good nights sleep. My problem now is - I travel to Australia every year, and have to endure this very uncomfortable complaint, and I would like to know if there is a cure during travelling - 20 long hours is a mighty long time. I would be grateful if you have an answer for me. Many thanks
Hi I am Chat Doctor. .  In my opinion you may avoid longstanding times, try to wear comfortable shoes or even slippers and elevate your legs during your trip as much as possible.  You may take a NSAIDs painkiller like Tylenol tabs or muscle relaxants in case of severe pain or emergency will be fine.
