Dear ,.don't worry but need to evaluate then treament Need to consult doctor  as there are thousands  reason behind chest pain ,chest pain may be because of heart problem itself or some other reasons too called as secondary  chest pain because of lung ,gall  bladder ,trauma ,injury , hormonal  disturbances ,  menses , many more reasons  without consulting doctor not possible to evaluate the cause . without diagnosis can't suggest treatment .

I agree with Dr Pallavi. But one more possibility may be there ,ie LRTI ( LOWER RESPIRATORY TRACT INFECTION) . You should go for chest x-ray to confirm.

I am really sorry to hear the problem your friend is facing. But you dont have to worry. I will need detailed history of your friend. I may ask some questions because i dont want to treat you blindly. Then I can write a prescription for friend which will help her to get rid of this problem. You dont have to worry she will be alright.
