Rolling out my thighs with a foam roller feels good at the time, but they’re tight again within days

Question

The outsides of my thighs and my calves get tight easily, so I work on them with a foam roller before bed. They feel much softer while I’m rolling and right afterward, but a few days later they’ve somehow tightened up again. It’s a little discouraging to feel like I’m back where I started even though I keep rolling them out. I’m wondering if foam rolling is only supposed to help in the moment, or if there might be another reason the same areas keep getting tight that I should look into besides rolling them out.

If the outer thighs and calves often feel tight, the cause may well be somewhere else.
I’ll explain with reference to the book “Anatomy of the Myofascial Meridians (Anatomy Trains)” by Thomas W. Myers, an American anatomy educator.
The muscle connections along the Lateral Line run from the longus and brevis fibularis muscles on the outer calf, to the iliotibial band and tensor fasciae latae on the outer thigh, the gluteus maximus in the buttock, the external oblique at the side of the torso, the intercostal muscles in the trunk, and the splenius capitis and sternocleidomastoid in the neck and head. These muscles are connected like one continuous line.
Therefore, working only on the outer thigh and calf will not lead to fundamental recovery. Stretching the entire Lateral Line is more effective. 
Stand upright, raise your arms vertically, and stretch by bending your whole body to the side.
Hanging from a pull-up bar can also help.
The detailed information about the Lateral Line is difficult and specialized, so I’ve focused only on ways to manage and improve your body on your own.
