thanks for writing to us.
if your angiogram is normal, and you still have typical anginal chest discomfort
, one possibility is microvascular angina
or small vessel disease
, but for this entity your stress test
(TMT/Stress ECHO/Stress Thallium) must be abnormal. if it is also normal which you have not mentioned, then your chest discomfort in all probability is non-cardiac.
joint pain/ rashes on nose and cheek can be due to a rheumatological disorder, which needs a clinical examination and consultation with a Rheumatologist/ physician. so consult the experts.
please write back if any of your cardiac investigations / problems need clarification.
