I think it s better if you mention the location of pain like front of things or back or side . but as per your provided information possible causes might be Front Thigh Pain Anterior thigh pain or injuries at the front of the thigh. An acute thigh injury comes on suddenly and includes muscle strains (tears) or contutions which are caused my direct impact or collision. Chronic or gradual onset pain at the front of the thigh occurs over time. The athlete may not be able to identify a specific moment the injury was caused. Back Thigh Pain Pain at the back of the thigh is known as posterior thigh pain and can be acute or sudden onset, or they may be chronic and develop gradually over time. It may also develop following an acute injury which fails to heal properly. The most common is a hamstring strain myalgia and nuerogenic origin of has to be rule out. I hope you happy with information. kindly rate it . thank you
