Back and chest pain is often closely related.
Injuries or degenerative conditions in the middle and upper back can also cause pain in the chest area.
Severe back muscle strain and muscle pain in the back or shoulder can cause heaviness and pain in the upper chest, too.
It is a good idea to get your spinal column examined with imaging techniques, checking for spinal stenosis, herniated disc, bone spur formation.
Anxiety and stress can lead to chest pains, too!
