Which are all the reasons for the Varicose ? How can we avoid and what are all the precautions to be taken ?

I too got this problem . I am under treatment with ayurvedic medicines. However the internal medicines clears the stomach and acts just to purify the blodd. main medicines are medicated oils to be applied externally on the affcted places and rubbed . We have to wait minimum 30 minutes and thereafter take bath with hot water. ( specially put hot water over the affcted places after applying the medicated oil and after waiting for 30 minutes). According to doctor it is coming due to poor circulation of blood on the places where the varicose is appearing. It may be due to more standing . normal exercise can be done. It can be cured only if treatment is stared at the beginning of the symptoms. Allopathy there is no internal medicines and only operation is the cure which is not 100 percent effective. It may reappear also . regards.
