Hello Doctor, my girl friend she is 26 years of age, she has 1 problem, anytime when she takes shower and if she keeps her hair wet for sometime she is infected by cold and she starts sneezing . When AC is turned on within 15 minutes she gets cold and starts sneezing. If she works in kitchen in water same thing starts. So doctor I am very concerned for her, I tried to speak to her in this regard and she said she has this from childhood and she says its due to weak immune system of her body. But I think that if this was case she would have got infected with not just cold.. but also with different diseases like fever , stomach ace, etc.. She also told me that the problem she is having of cold and sneezing is incurable. Kindly suggest what can we do in this case? Thank you and regards. Y Jagger.
