Hip and leg aches are caused by arthritis, injuries, growing pains and Legg-Calve-Perthes disease, according to Mayo Clinic. Chronic exertional compartment syndrome, pinched nerves, cancer and deep vein thrombosis may also cause legs and hips to ache. Additionally, pain can radiate to the legs and hips from other areas of the body.
Specific to leg pain, the most common causes include wear and tear, overuse, and joint, bone, muscle, ligament and tendon injuries, notes Mayo Clinic. Some causes are traceable to the lower spine. Poor circulation, blood clots and varicose veins also cause leg pain.
Polymyalgia rheumatica is an inflammatory disorder of unknown origin that causes pain in various areas of the body, including the hips, explains Healthline. Like polymyalgia rheumatica, the origin of fibromyalgia is also unknown. Fibromyalgia is a chronic disorder that causes unexplained, far-reaching pain in the hips and other areas of the body. Sciatica is a painful nerve condition that affects the sciatic nerve, which starts in the buttocks and hips and runs down both legs.
Depending on the cause of the pain, over-the-counter pain medications may effectively reduce pain temporarily, especially if the problem is a result of tendinitis or osteoarthritis, advises WebMD. Applying ice to the painful area for 15 minutes several times a day may help temporarily reduce swelling and pain. Prescription anti-inflammatory medications are also sometimes prescribed.
