Pain in my thighs when on my period. 😭

I get this crazy pain in my thighs when I'm on my period, it feels like there's a little person in my leg ripping up the muscles (no joke). It hurts so much. I take 6-8 extra strength gel advils a day because I can't take the pain. Any other suggestions for what I can do other than taking so much medicine? 🤔         I know it's unhealthy to take that many pills but its so painful....
