Pain In My Right Groin Area, Sometimes Feels Like Getting

Pain in my right groin area, sometimes feels like getting better then relapse of pain causes my having to actually lift my leg into the car or up on the bed, etc. also some burning pain in right knee joint. Noticed first after working out at gym and thought it was just a groin pull at first but it has been about 2 months since I first noticed the problem. What can I do to make my leg/groin well again assuming this is just a muscle/ligament pull?
