Testicle pain and pain in right leg.

It started two weeks back when pain suddenly erupt in my right leg (upper portion if more specifically I say). I visited nearby clinic and doctor told that it may be due to cold and gave medicine and advised to avoid cold water for bathing etc. I got cured in two days an got normal. Then suddenly a week later kind of pain arose in my right testical. I was a bit worried and visited doctor again. He said it might that my nerves have gone weak so he gave me another medicine and i got cured from it. But again pain came back to my leg and right joint. He again changed my medicines and pain got fine in the leg but it again started in my testicle. It is happening alternatively. What is the solution now? Should I be worried? Regards!
