My mother who has 65 years old has been coughing for almost 6 months. I have taken her to the specialist and he says that she does not have anything. The X rays shows that she is allright, but she continues coughing almost all day the doctor says that maybe it could be an allergy and he told her to use ventide spray(corticosteroid), but the problem is that she is diabetic. She uses the spry every three hours and a cough syrup, but she continues with the cough. It is really a problem because she has a probem with her vagina and every time she coughs her heart and her vagina suffers. Please would you be so kind to give me some advice. She uses candies for the cough and her mouth has been hurted. I am really worried. God bless you.
