Kati, as far as i know there is really not a cure for elephentatis???. your problem seems like eleph??? and it is caused by moquito bite. i am not sure what kind of specific symptoms you have but if your whole leg looks like elephants leg than it should be what i have said before.
Dont quote me on this, just google it up there should be plenty of youtube videos or other info to help you out.

--hope this helps.
