Had good appointment with private endo today. He didn't agree with treatment I've been receiving but agreed with you all - I should have had my antibodies checked. Is writing to my GP (whose letter of referral he was very impressed with) to request antibodies test, also to request a referral to a cardiologist to re-assess my angina.
Thank you all for your comments and suggestions. Feeling less anxious about it all & very grateful to have found an endo who listened, explained and was prepared to work with me rather than dictate. Not totally sorted yet but do feel we are getting somewhere.
