The impact of foot shock-induced stress on pain-related behavior associated with burn injury

•Mechanical and thermal thresholds were altered in both A/J and C57Bl/6 mice following burn injury.•Stress by itself increased mechanical allodynia, independent of burn injury.•Behaviors consistent with chronic pain after burn injury were apparent in both stressed and non-stressed A/J and C57Bl/6 mice.•Anxiety-prone A/J mice exposed to stress had a shorter recovery time with regard to mechanical allodynia compared to C57BL/6 mice.
