Have tried both to no avial, have better results using Capzasin, roll under balls of feet and you might try the lidoderm patch. Methadone alone is the best pain med I have used, but it has side effects severe constipation and urinary retention which causes prostate problems, had to catheter to urinate (have BPH). Have tried most PN meds, right now am detoxing using Tramadol been off Methodone for a week, came off Lyrica in Dec. Pain level at 4.5, am able to sleep. Life's a ***** then we die, Good Luck
