Hi Ninja22 and welcome
Other pains is common with back problems as all nerves going to the legs run through the lumbar & sacral regions. Back to legs--must go through hips. In fact, that is exactly where these nerves go....right next and around the joint where the femur (leg bone) meets the illiac crest (hip bone). So hip pain is common as well as buttox pain, leg pain (running down the backs or outsides)...calf and/or shin pain....soles of feet or top of foot pain.
There could be other things going on....try using the process of elimination. Example: if you are having trouble say--twisting your body this way or that. It could be the piriformis muscle. There is a test for that. I would say you have more than one thing causing these other pains. Keep tabs on when you get the most pains and where and when. Try to keep a journal. That will help you pinpoint just what is aggravating your hip (area) and what not do to and what you should be doing. All of this is the only defense you have for yourself so when you see the doctor...you will have a fluid and fluent history of your pains (with a written history) and it will give the doc a clearer picture of what you are going through and what the possibilities could be for your condition (diagnosis) and treatment.
A kinesiologist or an acupressurist or quite possibly a good massage therapist (like for sports therapy) are all trained to select and pinpoint muscle groups for testing and aiding. I suggest this as another way to somehow determine if your hip pain is related to your back pain....this is something you will need to take on yourself for yourself. Some doctors will say "they aren't related" while others will say "they are". Listen to your own body....carefully. That's the best advice I can give you on this. Good luck to you.
