Thanks for the query,
you might have developed a lipoma
It is the commonly seen in chest area.
On lifting arm the swelling becomes prominent as it is just under the skin.
If it is asymptomatic it can be left as such.
The best treatment is surgical removal.
Also get an USG done to find out the exact cause.
The nose problem is a common thing,
Its just thickened cartilage
and not a disease.
Please meet a dermatologist
Let me know if you have any other doubt.
