sorry to hear you are dealing with such an awful disease. it was thought i had lyme, when i was first searching for a diagnosis, because of the symptoms, but it turns out it was fibromyalgia. i empathize with you.
as far as the doc not prescribing pain meds... is this the same do who handled your med abuse? if so, i would search out a new doctor, who does not know of your past abuse.
since it is in your records (med abuse), possibly starting all over with a new doc would be your best bet. since you have been diagnosed, it will not be hard to be diagnosed again, because of the bloodwork showing you lyme. pain in the butt, but may be worth it to get the help you need.
best wishes to you.
