"i had surgery because because i blew out 3 disc.  i used oxycodone. at my request i started going to a pain management clinic. i was put on morphine and dilaudid was on them for about a year.  then they decided to try me on buprenorphine 8mg. pill under the tongue. i was also having caudal  injections which they gave me iv sedation. i also had a pain stimulator implanted .  i wish i never did that it doesn&#039;t help either. being on buprenorphine i have horrible swelling in my legs and feet i also can&#039;t sleep more than 3 to 4 hours at night. i take 100 mg of trazodone which still won&#039;t let me sleep.  i also have bruising  after my 4 th back surgery (laminectomy) they took my off oxycodone and started me back on 8 mg of buprenorphine. i hate it."
