"i got nucynta after i had surgery on my hand. i severed tendons and the recovery was awful. i was given norco and then also nucynta. the 2nd night i took the nucynta i started to feel strange. my heart was racing and i felt panicky. my bf asked me if i was okay and i couldn&#039;t answer him. i stared at him because i was trying to not have a panic attack. the feeling i felt is hard to explain. i just knew something was wrong and i was having some kind of reaction. finally i asked him to take me to hospital. once on the freeway i had a hallucination. i saw a 20 ft tall figure on the side of the road. i swear on my life. no other drugs were involved.. i don&#039;t drink and have never had this happen before. i was okay a few hrs later but it was scary!"
