Thanks for writing to HCM
You need proper clinical examination and investigations.
Raised feeling/swelling may be due to many reasons.It may be due to enlarged lymph node
After clinical examination,CT Scan
of thorax can be done to find out the cause.
However other causes of chest pain
should also be excluded.
You also need routine investigations like routine hemogram,RBS,LFT,RFT etc.
Hope i have answered your query.
Get well soon.
