Not all doctors are “total ignorants” when it comes to weight-training.
Though no one can positively say that lifting won’t make your condition worse, I feel that if it really is slight, it probably wouldn’t.
I actually have a slight lateral deviation of my spine - enough to notice when I do a rear double biceps pose. Lifting only makes my pain worse if I fail to stretch enough on a regular basis.
Strength training plus stretching equals strong, healthy muscles. But training without adequate stretching (esp of your hips, hams, erectors, and QL) could feasibly make your condition worse.
