[|Human|] My boyfriend has a slight indent (if I stick my finger into it it goes to about my first knuckle and its where the sternum is) in his chest, and he says hes had it since he was a little boy.  I was wondering if it could be causeing some of his breathing problems, and if he should get it checked out.
[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. The way you are describing chest deformity of your boyfriend, possibility of funnel shaped chest is more likely. It is commonly seen with childhood deficiency of vitamin D 3. Usually it is asymptomatic. Patient is not having any respiratory complaints due to this deformity. So I don't think his breathing difficulty is due to funnel chest. Hope I have solved your query. I will be happy to help you further. Wishing good health to your boyfriend. Thanks.
