"i went into the er today for severe pain in my shoulder. after an x-ray it was confirmed to be calcific tendonitis. i hadn&#039;t slept in 3 days because of the throbbing of pain. was given a shot of toradol and within 30 mins the pain went from a 10  to about a 3. it stung for about 20 min but after that was gone. no side effects at all. highly recommend for severe pain relief."
