Slight pain in the left rib area when breathing in, pain gets worse when i take a deep breath. pain also occurs when reaching down (putting on socks). i had allergies for the past few days with congestion and not i have this pain. i am 23?

for specific advice about the cause you need to discuss with your family doctor or primary care provider. As because chest pain like this that is worse with deep breathing or movement can be caused by a many problems, ranging from injury to muscle/tendons related to cough to inflammation of the connective tissue near the ribs seen with viral infection, to even pneumonia.
