However, runners are infamous for imbalances in their hip muscles. The most common weak ones are the hip abductors, the muscles on the side of your butt responsible for moving your leg out away from your body to the side. Lev Kalika, D.C., clinical director of New York Dynamic Neuromuscular Rehabilitation & Physical Therapy, tells SELF that since most runners run, run, and only run, they are constantly training their hip flexors and extensors through a very small range of motion. That can lead the hips to be unstable on the less-frequent occasions when you bring your knee all the way to your chest or thrust your hips forward.

Your hip flexors and psoas muscles help drive your legs up when you are running. To stretch these muscles, kneel on the floor and then step out forward with your left leg so that your left foot is on the floor. With your back straight, lean forward so that your weight is on the front foot and you feel a stretch in the hip of the back leg. Perform the stretch on both sides.
Enthoven WT, Geuze J, Scheele J, et al. Prevalence and "Red Flags" Regarding Specified Causes of Back Pain in Older Adults Presenting in General Practice. Phys Ther. 2016 Mar;96(3):305–12. PubMed #26183589. How many cases of back pain in older adults have a serious underlying cause? Only about 6% … but 5% of those are fractures (which are serious, but they aren’t cancer either). The 1% is divided amongst all other serious causes. In this study of 669 patients, a vertebral fracture was found in 33 of them, and the chances of this diagnosis was higher in older patients with more intense pain in the upper back, and (duh) trauma.

We all know the nursery rhyme about the hip bone being connected to the leg bone. It’s a simple song, but it contains a surprising amount of truth. The fact is that the body’s muscular, nervous, and skeletal systems truly are complex and intricately interconnected. Even a daily task such as walking down the street uses a complete network of a body’s muscles and bones, all of them reliant on each other. And when a strain, tear, or other injury happens in one part of your body, pain can often present itself in an entirely different part of your body.

• Gout. Gout is a form of arthritis that occurs when excess uric acid, a bodily waste product circulating in the bloodstream, is deposited as needle-shaped monosodium urate crystals in tissues of the body, including the joints. For many people, the first symptom of gout is excruciating pain and swelling in the big toe – often following a trauma, such as an illness or injury. Subsequent attacks may occur off and on in other joints, primarily those of the foot and knee. Less commonly gout can affect the spine, causing extreme pain, numbness and tingling. It can be confused with a spinal infection.

“Red flags” are signs or symptoms that something medically ominous may be going on. Red flags are not reliable, and their presence is not a diagnosis. When you have some red flags, it only indicates a need to look more closely. Sometimes red flags are missing there really is something serious going on… and sometimes they are a false alarm.18 Check off all that apply … hopefully none or few or only the least alarming of them!


The side of the pain on its own doesn’t tell us much, and most of the one-sided sources of pain are viscera that usually cause abdominal pain instead of back pain, or in addition to it. In other words, the only reason to worry about right or left lower back pain is if it is otherwise worrisome: if you have other red flags or significant non-back symptoms.
Don’t medically investigate back pain until it’s met at least three criteria: (1) it’s been bothering you for more than about 6 weeks; (2) it’s severe and/or not improving, or actually getting worse; and (3) there’s at least one other “red flag” (age over 55 or under 20, painful to light tapping, fever/malaise, weight loss, slow urination, incontinence, groin numbness, a dragging toe, or symptoms in both legs like numbness and/or tingling and/or weakness).

Often, a pulled or strained hamstring muscle can cause radiating lower back pain, and pain in the butt area as well. So, often, if you exercise a lot and are suddenly telling your friends, "My butt hurts a lot when I exercise it's likely because of a pulled hamstring. Often, a pulled hamstring can cause referred pain, such as upper thigh pain or upper calf pain and pain in the back of knee area as well. Symptoms of a pulled hamstring include severe pain during exercise and tenderness, pain in thigh muscles, sharp front thigh pain, and tenderness and bruising in the thigh area. The best pain reliever for hamstring pain is to use the RICE method explained above and to do stretches that relax the muscles of the thigh.
If you've been working out hard, playing football or other sports, or moving a lot of heavy furniture and are suddenly suffering with radiating lower back pain, chances are you have pulled muscles or strained muscles in the back. Often, strained muscles will cause a burning sensation in the lower back a feeling of having limited movement ability. Doctors prefer to limit prescribing of opiate pain medications and may give you an alternative medication with less risk of becoming dependent.
Note: Exercises that strengthen the hip flexors also involve contracting (shortening) these muscles. So if tight hip flexors are a problem for you, it might be wise to limit how many direct hip-strengthening exercises you perform. These exercises are more geared toward people who have been told they have weak hip flexors that need strengthening or are looking for targeted exercises to build more power and stamina in the hip flexors.
But mobile hip joints don’t just relieve pain. They’re also essential for walking, hiking, running, jumping, dancing, playing sports, and pursuing virtually any fitness goal safely and effectively. Want to develop stronger, more muscular legs? Hip mobility allows you to lunge and squat more deeply so you can reach your muscles’ potential. Want to avoid injury? Hip mobility improves range of motion so you can perform exercises more safely.
The main work of your hip flexors is to bring your knee toward your chest and to bend at the waist. Symptoms associated with a hip flexor strain can range from mild to severe and can impact your mobility. If you don’t rest and seek treatment, your hip flexor strain symptoms could get worse. But there are many at-home activities and remedies that can help reduce hip flexor strain symptoms.
