It's been gradual, noticing it for the first time a few months ago and visiting a chiro. and just recently a PT.... No "incident" of injury felt, but my job includes standing, repetiveness and a moderate amount of waist-level lifting.
The lower back ache is felt ONLY when standing for long periods of time. Usually a few good stretches (as directed by PT) give relief. But, after an hour the tightness returns. It especially is uncomfortable reaching down or going down (to sit) after this period of standing.
My medical doctor didn't get an X-ray at this time, diagnosing as a soft-tissue/ lumber strain. Just going with the conservative treatments for the time being. Have no leg pain or tingling or other symptoms. In fact, being active (walking/ biking or whatever) bring no discomfort at all.
Anyone have any input/ suggestions &/or experience with this kind of thing? With no improvement in the next couple of weeks, will probably head back to the doctor for more tests.
