lower back pain after lifting legs in the gym.

Soreness- Seems the weight is too heavy for what you are lifting. Your form might not be correct as well. Lower the weight and work on the form. Should go away in a few days.

2 weeks is a bit long for normal muscle soreness. Have you done anything to aggravate the muscles (probably spinal erectors and/or glutes) since then? If not, and it doesn't clear up soon, consult your physician.

I am guessing bad form during deadlifts or squats. I had some of this myself last week, but it should go away after 72 hours or so if it's just sore muscles. Are you experiencing muscle tightness or something else?

I had something like that once or twice and it went away after a couple of weeks, but that doesn't mean that your pain will go away. In my case I think it's just that I had muscle soreness and didn't really ever rest my back so it took a good while to disappear. If you walk around in the course of your day and if you're still lifting with free weights, then you're still using your back. If I were you, if you can't afford to see a doctor, I would really rest it for three weeks....only do upper body in work in a sitting position, if anything...not go on long walks...keep it warm...take ibuprofen regularly...and hope that it's just soreness and goes away. Maybe when you squat you fall forward when coming out of the hole and then haul the weight up with your back, rather than rising up evenly, and maybe when doing lunges too you lean forward too much. Sumo deadlifts and front squats are easier on your lower back. But really, if you're uninsured, I would do nothing until the pain goes away if I were you.

as someone who has dealt with back problems in the lumbar area of a long time, you need to be more careful. if you go to a doctor, all they are going to do is give you an anti-inflammatory, like prescription strength alleve, and tell you to rest it. as long is there isn't pain actually going down your legs, signifying a nerve related injury, then you will be fine.. it is very easy to herniate a disc in your lower back while lifting weight like that with your legs. and if you are prone to lower back pain then i would look up some exercises on the internet that can work your legs without putting so much pressure on your lower back. a good exercise to do is to lay on your back and slowly bring your knees up to your chest. you can use your arms to hold your legs to your chest for 30 seconds. repeat it a few times in the morning and at night. additionally, lay on your stomach and extend your back by pushing up with your hands. sort of like a push up, only leave your pelvis flat on the ground. finally, take ibuprofen or alleve (2 pills) twice a day for a few days. hot baths are great to relax your lower back muscles.

The longer the pain lasts, the less it looks like a muscle / soreness problem. FWIW, that's how my back pain started (mild soreness aggravated by some positions) and I ended up needing heavy pain meds and surgery on my L5/S1. Follow metamush's advice, especially the back extensions.

IANAD. But I could squat one. It would help if you clarified "squats, lunges, etc." Delayed onset muscle soreness is a different kind of pain from a lumbar injury. Everybody learns the difference eventually. You can certainly injure your lumbar spine rather easily in the squat, or the deadlift, or several other lifts if you relax your spinal erectors and lose lower back extension. At 2 weeks out I can't imagine it's DOMS, but you don't say if you've done any training since then. In any case, ibuprofen will help with the pain and inflammation. You can take 600-800 mg 3-4 times a day if necessary, but should use the lowest effective dose. If possible you should not stop training, but ease back into things. Use very light weight and make sure your form is correct. Always maintain a hard lumbar arch during the squat.

on that day i did squats, leg press and lunges. no deadlifts. i suspect the squats were the culprit tho.

holympus's advice is pretty good, but I can't agree that you need to do a few hundred air squats before doing any with weight. One must always balance caution with ambition in working out -- you should be careful, but not so careful that you never try something hard. A heavy weighted squat is different than an air squat, and the weight can actually make things fall into place form-wise. Doing air squats all day is a waste of time if you're trying to get strong. Read Starting Strength and squat heavy with your back in extension and you'll be ok. (I weigh 175 and have squatted 305.)
