What causes tingling sensation in the lower extremities?
Patient: Hi, I’ve been diagnosed with spinal stenonis, within the past 10 weeks, I have gone thru rehab for 30 years of chemical dependency from opioids, benzos, muscle relaxants & antidepressants. Consicuently, I am experiencing increased pain lately. My concern is that I am feeling sensations and tingling in my lower extremities. Should I be concerned? Doctor: Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.  That is the result of the spinal stenosis which is usually due to arthritic and common degenerative changes in the skeletal structure which is an aging process and not likely to be strongly associated with the chemical substance abuse issues.  You should see a neurologist for a full scale examination and participate in aquatherapy and/or land physical therapy as recommended in order to reduce or slow down the pain and other sensations you describe.  Osteoarthritis (likely problem you have) is not curable but it is definitely manageable with proper diet, exercise, and other precautions.    Hope I have answered your query. Let me know if I can assist you further.
