I'm a 26 year old female, I have severe pain during periods accompanied by continuous vomiting for 1-2 days, I keep a bucket beside my bed to vomit as I keep vomiting every 5-10 mins. The pain is very severe spanning from my pelvic region to my back and legs, I can't eat anything for two days and my life comes to a complete halt. I've been bearing this for last 10 years now, please suggest a proper solution. I have consulted a lot of doctors, done hormonal treatment too, but the medicines only work for a month or two, after that it comes back to the same problem. I take maftal spas and ondem MD8 at the start of my periods. I've done my tests for pcos too, but it's negative. Please help
