My mother aged 47 yrs, underwent angiography few years ago. She had been feeling chest pain every now and then since that angiography. Last month, out of nowhere some boils occurred over her forearms and spread all over her body the same night. I took her to the hospital some injection were given to her. Boils have faded away but she had been complaining of severe chest pain more often than usual and the instances keeps increasing everyday. Doctors at hospital just give the medicine and carryout the blood test. Please suggest what should I do in this situation?
