I've noticed that the past few months, I've had some tightness in my hip flexors. I have a sit-down job and I assumed this would get better once I started exercising regularly. I've been doing the treadmill for a half-hour for five days a week, and occasionally add supplemental exercise like rollerblading, walking outside, or riding bike. I've been exercising like this for about two or three weeks, thinking the tightness would naturally work itself out. It hasn't yet, but it's also not getting any worse. I admit I haven't done enough stretching, which would probably help.
Has anyone else experienced this, and if so, what helped?
How long should it take for these muscles to loosen up?
At what point does one decide they should go to the doctor for it?
Thanks in advance for any input, comments, or suggestions.
