you say no amount of painkillers work
but I find if you combine some paracetamol and some ibuprofen that that knocks the edge off, you also have to keep taking and get those does into in time. It is called pain management.

Also if you are cramping some gentle exercise can help like a liitle bit of yoga or walk around.
