Thanks for writing to us.
Given your symptoms, it seems that we are looking at a muscular injury or a nerve injury
which could have been precipitated by trauma or some unusual activity. The tingling
is probably become the same nerves supply the left side of the chest and left arm. Thats why pain in 1 area is referred to another one.
At this stage, what we need to do is hot compresses . Also apply some diclofenac
gel locally. If the pain still persists, we would need to get you seen by a physician who can do a Nerve conduction velocity test to find out if the nerves are fine
Hope that helps
