I am just getting over a stress fracture in my lumbar vertabrae area ofmy back.  The pain started in October and I received 6 weeks ofphysical therapy.  I have experienced a crumbling feeling in mylower back over the last few weeks, but do not understand what thiscould be.  I continue to take Calcium and Fosamax for my osteoporosisand I am 60 years of age.
Hello, I have studied your case. I will advise you to do MRI thoracic spine, HRC [CHEST] and EMG- CV [nerve conduction study]For these symptoms analgesic and neurotrophic medication can be started. Till time, avoid lifting weights, you can consult physiotherapist for help. Physiotherapy like ultrasound and inferential therapy will give quick relief. I will advise checking your it B12 and it D3 level. I will advise consulting orthopedic surgeon for clinical examination and further investigation. Another possibility of lower back pain is kidney related pain which can be ruled out by Ultrasonography and renal blood test. Hope this helps. Wish you a speedy recovery.  Take care
