Thank you Sue, Amigo Rosie and Ljc. I did wonder about a false hypo Sue but I had the same sensation again this morning and my Bgs have been a wonderfully smooth line in the 7's for the past 24 hours. Thanks for the warning Amigo. I went to the GP - blood pressure was 149/80, heart rate was 110,but I think she thought that I was nervous although I did point out that I have supra ventricular tachycardia and that the tablet I'd had for this earlier should have brought the heart rate down. She said two or three times that I'm a mystery but had no other suggestions apart from ordering an ultrasound for the pain but she said that could take several weeks. She said that if the pain gets worse to go back.
