I have swallowing in whole right leg from last 2 years without any reason but no pain in leg. If I walk or sit much more time then swallowing also increase.And in morning swallowing decrease little bit after doing 8-10 hrs rest in night with kept pillow under my leg. I have done liver, kidney,sugar, blood ,xray,echo,abdenome urtrasound and color dropper test but no root cause came out . So please tell me the reason of swallowing.
