I have had 4 back surgeries 3 on l-4 l-5 and one on c-4-7. I have been on pain meds for 3 yrs. What kind of withdrawal will I go through and what can I do to alleviate the symptoms of the withdrawal?

More info needed. You are wise to be concerned about withdrawal effects when on chronic pain medications. However, specific concerns and specific advise will depend on which pain medication or medications you are taking, as well as dosage and frequency. Best to see a physician who specializes in pain management.
