What causes burning sensation in the lower back?
Patient: I m having a burning sensation in my lumbar spine area. Also tingling there and throughout my back (upper and lower). (for the last few weeks). I saw a chripractor and they said in my lubar spine was a problem. Also had some tingling in my right hand and some numbness in my feet. Today it was worse. Woke up and noticed downward arrow bruising in the sacrum area. Like 5 or so dots in the triangle shape. Cannot sit today at all makes it a lot worse. Standing/walking is fine. Lying is less bad than sitting. Doctor: Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.  Overall picture suggest peripheral neuropathy , may be due to deficiency of vitamin B12. The bruising could be related to minor bleeding in sacral area due to minor injury or irritation. I would suggest getting blood test for serum vitamin B12 and then start vitamin B12 supplementation in injection form. Wait for the progress in sacral bruising to progress or regress .   Hope I have answered your query. Let me know if I can assist you further.
