Why do I feel like my muscles are twitching or thumping in my thighs and butt when I exercise?
After I walk briskly or jog at the gym I feel like my upper thigh and butt muscles are twitching or almost thumping under my skin. It doesn't hurt at all, it's just strange. I'm not sure if it's happening because I have cellulite in those places? I'm not overweight, just average. Just wondering if anyone knows what this is and if they have felt the same?
