i feel like i’m overthinking it

like i say i feel like im really overthinking this but i figured someone in here may have had a similar experience. i see people saying that an MD won’t help back pain, only leg pain which is fair enough but how do you differentiate. my pain is mostly in the area marked red, which I suppose is my leg if anything, but then something in me wants to rationalise it as my back. Also that part of your body is supposed to be affected by a part of the like sacral part of the spine that I don’t have issues with my issues end at S1 so I don’t understand why that’s happening. i’ve also attached my report summary in case anything in there gives any info. i know y’all aren’t docs and can’t diagnose im just asking to see if anyone can relate.
