Symptoms that may accompany thigh pain vary with the underlying cause and include swelling, joint pain, muscle spasms, bleeding and a burning sensation, according to Healthgrades. Easy bruising, pain or tingling in the toes, and change in gait may also occur along with thigh pain.
Symptoms of thigh pain may affect other body areas, including neurological and cardiovascular systems, explains Healthgrades. Flu-like symptoms, including fever, headache and sore throat, may occur together with the condition. Rarely, the pain may signify that an individual has deep vein thrombosis, a condition in which blood clots in legs move to the lungs, leading to pulmonary embolism.
In rare instances, painful thighs may show that a person suffers from serious conditions such as fracture and infection, according to Healthgrades. Individuals who experience chest pain, deformity of the hip, thigh or knee, or extreme swelling with or without thigh pain should seek immediate medical care. Other life-endangering symptoms include wheezing, difficulty breathing, cold leg and fluctuations in the levels of consciousness.
Causes of thigh pain include injuries, such as abrasion, laceration and bone fracture, and infections, including cellulitis, which is a serious infection, states Healthgrades. Diabetic neuropathy and peripheral neuropathy, a disorder that destroys nerves around the brain or spinal cord, can cause thigh pain as well.
