Allergies (I think)

Patient: Hi previously i was put on oxycondone 10mg twice daily for a spinal tear and a herniated disc, whilst taking them i returned to my doctor with trouble breathing and red swollen blotchy lips. Six weeks ago my doctor ceased me from taking the oxycondone, but i still get red swollen blotchy lips that are extremely sore making it almost impossible to smile as the skin feels like it is so tightly pulled, I also get very fatigued regularly associated with stomach cramps at times. Any advice that you can provide me would be appreciated.Thanks.
