hello and welcome to HCM,
There are many causes of tinnitus
or the whistling in the ear and many of the cause may cause both chest soreness and tinnitus!
Many times tinnitus can also occur after exercise but this usually disappears soon
if the whistling persists then you need to undergo a complete evaluation of the known causes of tinnitus especially the vascular causes.
hope he recovers soon
