I'm a bachelor living away from my home. My food intake have reduced way too low and when I started to do squats I got leg pain on my knees slightly. But later one day I skipped my meal for almost till dinner. That was when my leg had severe pain for 2-3 days. And it was not on the knees but only the right leg; starting at the abdomen of the right leg till my thighs, only the leg/thigh alone. It has occurred twice or thrice now. Please advise.
