Lump on lower left rib ?

Question

I have a lump on my lower left rib I am 16 years old. (Lump has been there for 2 months) I went to my doctor and he said it's nothing but a muscle and my rib bone is the lump... How do I help this pulled/torn muscle? and does this dianoisis sound reasonable to anyone?

Thanks

This is something that could be serious however since you seemed  to have doubts why not get a second opinion .Good luck and have a great day .
