Hello. I have had no injury or incident - other than one morning I woke up with severe low back pain; I had "thrown my back out" somehow while sleeping? It was very painful and difficult to move.
After weeks or months I was able to move around and function normally again - but since then I can't stand for longer than 5 or 10 minutes without my left outside/front thigh going numb and burning. It's seems to be in the lateral femoral cutaneous nerve. And the pain in my lower back (sacrum area is where I feel it) gets worse and worse the longer I stand.
I have full mobility and strength. I am fit and slim (exercise every day, eat health, sleep great). I have no pain when laying down so no sleep trouble, and get relief when sitting or squatting down or bending over.
MRIs show I have a couple herniated discs (around L4/5 area). Looking at my spine when bent over, the lower area (L2/3ish area) looks crooked. If I wear a back brace I can stand for hours with no leg symptoms but achy low back.
I have tried chiropractors, physical therapists, acupuncturists, injections - nothing works. Any ideas? I'm thinking about trying an inversion table? I have been living like this for 7 years. It would be nice to go to an amusement park, fair, art show, etc. again and feel like a normal person - with no pain.
Thank you so much for your time and any ideas you may have.
Everyone is missing something and it's difficult for me, not being able to examine you, to pinpoint it.
But firstly, are you doing any lower back, sacroiliac and hip joint exercises every single day? Before you get out of bed is my recommendation; they take less than two minutes. If no one else can help you, you have to look to helping yourself; as you are doing in writing this letter.
Secondly, ask hubby to kneel down behind you and place his hands on the iliac crests; are they clearly level? Pain predominantly with standing and dawdling as at the art show says to me, check the leg length. Has anyone considered that, mentioned it? A simple inexpensive lift in the shoe can make a huge difference. Sitting would relieve the pain.
A pinched LFCN in the groin is a possibility but then running your thumb through the groin is usually very painful. Is it? Using a needle is there actual sensory change in your thigh? Compare sides.
Forward bending relief suggests to me degenerative facet joints; does bending backwards, or to the side bring on the lower back pain or tingling in the thigh?
Bounce on your knee; is there any weakness of the quadriceps muscle in the front of the thigh? Do you know if there was any change in the knee jerk reflex?
Sitting in a kitchen chair, flex your head onto your chest, and then slowly raise first the normal and then the naughty leg parallel to the ground. Is there a significant difference?
Do you have pain when coughing or sneezing?
There really are quite a lot of possibilities but the question why is it not responding to any form of treatment? An uncorrected short leg could certainly be the problem.
An inversion device may certainly help; get one with comfortable binding around the ankles and don't invert without someone else in the house.
Give me some answers, and let's take this further.
