period pain
"I take mefenamic acid for endometriosis. I have to say it has helped me greatly. I definitely notice if I don"t take it. It's an ant-inflammatory so I take it everyday. You need to build it up in your system it doesn't work as instant pain relief. So if you take it for your period you need to start taking it the week before. It is in the same family as ibuprofen so it can upset your stomach. Make you take it with food and if you are going to be on it for a long time. Take something to protect your stomach. I can't say it helped with the heaviness but the pain definitely."
