Hello,
The causes of your pins and needles and numbness along the leg and foot is are:
1) Failed back surgery syndrome
2) Sciatica or sciatic compression
3)
Spinal canal stenosis
4) Herniated intervertebral disc
The following are few treatment options:
1) NSAIDs like Ibuprofen and
Aceclofenac taken twice daily can be used along with muscle relaxants like chlorzoxazone
2)
Pregabalin (Lyrica) 75mg once daily for 1 month
3) Opioid analgesics like
Hydrocodone, Oxycodone and Tramadol can also be used for pain relief
4)
Physical therapy would relieve pain by strengthening back muscles.
If the pain doesn't subside, you have a steroid and local anesthetic injection into the lumbar facet joints. If all the above measures fail, you may discuss the surgical options with your orthopedic surgeon.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Pallavi M., Anesthesiologist
