I've had 2 bad reactions in the past week after taking hydrocodone and tramadol. could i suddenly be allergic to both? no history of allergies to eith

Intolerance: Since no description on the reactions or time of onset after taking these pills , it is difficult to tell . However, allergy to these drugs are rare if happen at all . Most adverse reactions are intolerance instead of allergic to these types of drugs. Perhaps a lower dose can be tolerated but you need to talk to your doctor before taking them again.
