I fell resulting in Lisfranc foot injury on Mar. 11, 2012. Doc prescribed hydrocodone for pain until swelling subsided enough to perform necessary surgery. Surgery was finally completed Mar. 30, 2012. In hospital on morphine for 4 days; back home for recovery with hydrocodone. Looks like I'll be on it for awhile, since pain can still be quite debilitating. How can I avoid addiction to the pain meds?
