in november 2017 i went to the hospital because of this sharp unbearable pain i woke up with and in my right side that spreads from my lower right abdomen to my lower right back and hip area. i had an ultrasound and blood work that came back normal. they gave me an IV with saline and the pain went away. the pain lasted the entire day. since then every once in a while the pain comes back but it does not last as long as it did the first time and it is not the same level of pain. today the pain started again while i was doing some chores at around 9pm. at first i thought it was the same as always and it would subside. but it continued and got worse it is now 1am and the pain is at the same intensity as it was the first time it occurred, maybe worse. what is the pain and what do i do ? should i go back to the hospital?
