"i having been taking tramadol for the past two years for abdominal pain due to excessive scar tissue from 5 surgeries.  it has been great for everyday mild pain.  i have no side effects at all.  unfortunately no loss of appetite!  however, when my pain is severe this doesn&#039;t quite cut it and it hasn&#039;t ever really done anything for my back pain, which tends to flare up often.
