Hi,Thanks for your query ...Causes of the thigh pain are diagnosed with help of physical examination, x-rays, CT scan and studying the medical history of the patient. Overused thigh muscles or an irritated nerve need to be rested for some time. This will prevent any further aggravation of the pain and ensure faster healing of the damaged tissues. To give a soothing effect to the burning pain, ice can be applied several times in a day. Medicines like anti-inflammatory medicines, corticosteroid injections and muscle relaxants are mostly used to bring down the painful symptoms. If there is some swelling because of muscle injury, then use of compression bandage is recommended. Physical therapy is also proved to be useful as it stretches and strengthen the muscles really well. In most cases, these conservative methods of treatment are enough to heal up the injury related problem. However, if the muscle fibers are badly torn or the hip and thigh joint is in badly damaged condition, then surgery is required to repair the damage. Sometimes, sciatic nerve is pressed so badly that it has to be released with the help of surgery. In case, there is some underlying health conditions, then it should treated properly in order to provide relief from thigh pain. Any injury related thigh pain can be prevented by toning up the thigh muscles with exercises. Those who are overweight should decrease their body weight to ease off the pressure form thigh muscles. Many a time, it happens with us that we ignore a dull thigh pain for a long time and it get aggravated into a sharp thigh pain. That should not happen.....Regards, Dr.D.P.Bura
