What causes severe pain in the lower back and inner thigh?

I have severe pain in my lower back running through my right inner thigh and outer hip. Deep, aching pain. My thigh feels like it s going to burst. It hurts the least when I bend forward at the waist at least 90 degrees. What might be the cause(s)? I do not remember doing anything out of the ordinary to cause this. I woke up 3 mornings ago with this problem.

Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.

I think you are suffering from ankylosing spondylitis with nerve compression. You can take muscle relaxants, like Thiocolchicoside with Methylcobalamin.

I hope this information has been helpful for you.

I am having acute low back pain, started last night with restless legs and severe pain in thighs and calves. Difficulty sleeping last night because of pain. Little relief when lying down on my side. Tried some heat last night. Visiting our grandchildren, lifted my 2 year old grandson yesterday several times, but did not experience severe pain until late last night. We return home to California on Thursday. I have been having severe RLS, and just started on Gababentin. I am 69 years old and a female.

I was diagnosed with stage 4 kidney disease in August. I also had a serious kidney bleed after my kidney biopsy around the same time. For the past 4 days I ve been getting a deep slow onset pain in my thighs, hips and lower back. It comes and goes hourly. I am using a heating pad and it only helps sometimes. Any suggestions would be helpful. Thank you

Extreme hip, thigh, and lower back pain, accompanied by sever chills with uncontrollable shaking for about an hour. Pain has continued off and on and I am feeling quite fatigued. I stayed home from work yesterday because I could not stand long enough to get ready for work. I went to work today, but it took quite a bit longer than usual due to the hip and thigh pain. I also had some minor upper left chest twinges. I have spinal stenosis in the lumbar region, and the back is curved to the left. It feels like flu symptoms but I have no respiratory symptoms. Is this something I should go to my GP about? Sorry, I did not realize this was a pay for answer service.
