Why is my hip always tight?

Why? There are multiple reasons. You could be sleeping all night long on the same side or one leg could be longer than the other. The list goes on. Let's balance them out. Lie on your back with your feet flat and your hands inter weaved behind your head. Drop your knees slowly to the left and take 5 deep breaths. If you want to increase the stretch take your right knee on the upside of your left leg and drop a little lower towards the mat. It is key to take full deep breaths into your ribcage and relax into the pose.

Constant tightness in your hip can stem from a multitude of factors. If you've been cleared by a physician for activity, the first thing you can start to take note of is how you sit throughout the day. The body tends to adjust to the positions you put it in frequently. For instance, if you sit all day, your hip flexors, or the muscles that bring your knees to your chest while standing, will shorten. Walking around with shortened hip flexors may cause back pain, knee pain, etc. That said, take note of your various prolonged postures throughout the day. If you're not sitting properly, or tend to sit and lean towards one side, straighten it out!

The next thing you can do is buy a foam roller, and put it to use on the areas you feel are tight. Lay on the roll, and slowly find the spot that is most tender. Keep it there for at least 30 seconds.  After you've laid on the foam roller, stretch the muscles you just foam rolled for at least 30 seconds. The foam rolling will not be comfortable, but after you've finished, you should see some relief.

You may have a tipped pelvis that is creating a structural imbalance and tightening of the muscles that move the hip.  Do you have one leg shorter than the other? Do you lean into one side more when standing? These and other signs could indicate a misaligned or subluxated pelvis or spine.  The restoration of motion to a previously fixated joint leads to normal joint function and physiology.  A spinal checkup from a chiropractor can determine if this is your problem.
