Thanks for your question on Healthcare Magic.
I can understand your concern.
Your all symptoms are more suggestive of
stress and
anxiety because of the fear of lupus.
But better to first rule out heart diseases and lupus.
So get done ecg, 2d echo and Holter monitoring (24 hours continuous recording of Ecg). If all these are normal then no need to worry for heart diseases.
Also get done ANA (anti nuclear
antibodies) profile to rule out lupus and other
connective tissue diseases (CTD).
If ANA is also normal then no need to worry for lupus.
Consult psychiatrist for counseling sessions. You can may need anxiolytic drugs too.
Don't worry, you will be alright. Avoid stress and tension, be relax and calm.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
