I take mefenamic acid which I get on prescription from the GP. About 4 years ago I started getting such horrendous pain I found myself screaming (quite literally), and unable to stand up, so going to work was a no-go. In short, it was severely impacting my ability to lead a normal life. Prior to the prescription meds, I'd taken far too much codeine during one horendous period, and knocked myself out only to wake up 13 hours later with the hot water bottle over my ankle, and a huge blister on my leg which has now left me with a scar and resulted in a trip to A&E and 2 subsequent nurse appointments to get the hole in my leg seen to. I felt that the burn was taken far more seriously than the pain from period cramps that caused it... And almost had to beg my (male) GP for something stronger, because quite frankly ibuprofen, paracetamol, codeine... none of it touched the surface of the pain.
Go to your GP and see what they can offer would be my advice. I do know there are risks with mefenamic acid, stroke being one of them, so I'm not suggesting anyone necessarily ask for those tablets, and I'm not a doctor!
Since then, I've also had the hormonal coil fitted last Dec and that has massively reduced my need to take the prescription meds, and I wish I'd had it fitted ages ago. I think the non hormonal coil can cause the opposite though, and can create more pain. But again, I'm not a doctor.
I think unless a person has experienced for themselves just how debilitating period cramps can be, it's impossible to convey just how absolutely awful they are. I ended up living in fear of my period each month, which is no way to live. Prior to this, I just had mild pain and to this day have no idea why they suddenly turned out to be so painful.
You will have options, so don't continue to suffer x
