I suffer from severe menstraul cramps with abdominal pain, hot flashes, nausea, leg pain, back pain and sometimes even fever. I have to take a day off from work during my periods. Earlier, i used to take over the counter pain killers which helped a lot but since i donated a
kidney, i have been advised not to take over the counter pain killers. Could you please advise me some kidney safe pain killers to help me deal with the pain. Thank you.
