He had a peak&trough test after asking for a raise in methadone,it was normal. He was told that they treat addiction not pain and was told to go to a DR.for pain.His DR. perscribed methadone and another narc. for breakthru pain.He is now pain free but very afraid that this may be considered Doctor shopping.He is afraid to ask because he doesn't want to lose either.After 15 years on methadone and 6 yrs with pain clinic neither can provide him with enough medicine alone.He is over 60yrs old and afraid of losing his medicare&SS if this is considered 'shopping'.He asked a retired atty and was told that since one is treating addiction& the other is treating chronic pain that he is OK. Not sure the 'retired' atty is up to date and is correct.Is this DOCTOR SHOPPING??
