The first thing you have to do is consult with a specialist - a urologist. You have to get over the embarrassment in order to get this medical issue taken care of.
To me, it sounds as if you have an ascending testicle. If the testicle is still viable or in good condition, it may be possible to move it back and attach it into the scrotum. The problem I see with this is that you waited too long and this might not be an option anymore, which is why you really should seek medical help from a urologist who knows how to do this type of surgery.
