Hello,
Welcome to Healthcare Magic.
I have read your question fully and understand your concerns.
Chest pain radiating to back, to one or both sides of neck/jaws or to one or both arms is likely to be
angina. Do you have any other symptoms like sweating,
nausea, palpitations, faintness when you get the chest pain? Angina is a condition where the muscles of your heart are not receiving enough blood supply/
oxygen due to blockage or spasm of the blood vessels of the heart. If the blockage is severe it can lead to
heart attack.
I would advise you to see your doctor as soon as possible. He would do a complete evaluation and also run some tests on you like ECG, Treadmill test, ECHO of the heart etc.
I do not think there is any association of hives with chest pain. If it has occurred only once it could very possibly be a coincidence.
I wish you a speedy recovery.
I hope this answer has helped you.
Thank you
Regards
Dr Sunita Sayammagaru
