I got referred for an ultrasound which found nothing. I know I'll get a text from the GP with 'no further action required'. I have severe period pain which has worsened over the years and mefenamic acid barely touches. I have a recurrent tugging sensation in my lower right abdomen.Exhaustion, nausea, headaches. Only diagnosis hypothyroidism and vit D deficiency (3 years ago). The pain is to the level of almost going to a+e. I'm absolutely sick of it. Any idea's?x (def not pregnant)
