I Have Weight Issues And Can Never Seem To Find

I have weight issues and can never seem to find a diet and exercise plan that will help me lose the weight... I have recently started working out more and also working a pretty laborious job... For the past 3 days, I have had a constant numbness in my outer left thigh. There is no other pain or discomfort anywhere else. I'm not sure if this is just a simple pinched nerve or something more serious like diabetes.
