Welcome to HealthcareMagic forum.
As per your MRI
scans, there are enough causes to explain the back ache. Now since you report worsening of pain and referral pain to the leg, I fear the condition may have worsened.
Back problems such as yours are managed conservatively with help of analgesics, physiotherapy
and rest. Intrathecal steroid
injections are needed in some cases. When there is no improvement with conservative line of management or if there is worsening of complaints with neurological involvement, surgical treatment
would be required.
Hence I encourage you to visit a spine surgeon
or neurosurgeon. A careful examination of spine, neurological examination and probably a repeat of scan might be needed. If the worst is suspected, you might need surgery. Else you may discuss about intrathecal injections and physiotherapy with them.
Hope this helps. If there are any other information’s which you like to share, you are welcome.
