<s>[INST] MY mother aged 58 years is suffering from lower back for 3 years but since last couple of months, the pain has spread to both of her legs and below knee she feels absolute numbness. Doctor has advised her to wear cotton shoes and not  to remain bare footed as any injury at this stage would lead to complications. Request Neuroloist to sugest for further medication. She is heart patient and non diabitic. She is little over weight. [/INST] Hellos per your description of the clinical symptoms it seems that your mother has a PIED (prolapsed intervertebral disc) with radiculopathy, which means there is a nerve root compression at some level of her spinal cord and the pain is radiating to her lower limbs. If I were the treating doctor I would have suggested an MRI scan of her spine (lumbosacral region, being the most common) and with relevance to her present symptoms and other medical conditions a Decompression surgery may be required. Relief of symptoms in this kind of surgeries are prompt and magical. Hence, I would suggest you to visit a spine surgeon (orthopedic or euro surgeon), get her evaluated and proceed accordingly. Thank you. </s>
