With your history of back problems, this could be a new symptom related to something happening there. I do hope you will call the doctor and get this investigated. I ache right now just thinking about what you are going through. I hope you get relief soon.
The Problem is the inside of the left thigh, and sometimes radiates into back of the leg. It only hurts when I have to move my leg into another position. There is no burning.
I have Chronic Myelogenous Leukemia, but I have been in total remission for 10 years. I get tested constantly for that. I have had the Arthritis for many years, and sciatica in the right leg that comes and goes.
My other issues are back problems, hypertension, diverticulosis. The back problem has given me a lot of trouble for years. I just have to move wrong, and I am in a rib belt for weeks till I am back in alignment.
I no what it is like for me when I feel like I can't take one more thing and yet, here it comes. It can be overwhelming. Sometimes it feels like your life revolves around new symptoms and doctor visits. Yet, we can't let it go. We have to dig down deep and face the situation, pick up the phone and make yet another doctor appointment.
You mentioned other health problems, do you think this could be related? Without knowing what else is going on, what meds you are taking and more about the pain (is it shooting, burning, does it run down the back of your thigh or the front or is it the whole thigh?) it is hard to say.
It sorta sounds like you may have a pinched nerve, but only a doctor can tell for certain. I hope you will make the call to see a doctor and write us back to let us know what you learn. We are here to help and support you. You can write to complain or ask a question, we'll be here.
