Pain
"Been on Opana now for roughly 1.5 years.  Stool movement is difficult and most of the time you feel bloated.  With that being said, pain is not problem with current medication.  2x 20mg ER (Morning, Night) with 4 x 10mg IR for break through pain.  I have L5 S1 area problems.  Sweats are also difficult at times in heat.  "
