Stiff neck and shoulders
In summer, we tend to stay in an air-conditioned room and keep cooling our body. That stiffens the blood vessel and the muscle, causing soreness around the neck and shoulders.
But that can be a sign of heart diseases.
The organs don’t have a lot of nerves not to affect our daily life. For example, if the heart have a lot of nerves, we have to react to every heartbeat.
Instead, the spine where is the same level as the organ detects pain or other symptoms.
The level of the heart at the time of fetus is the same as the shoulder, but it lowers as we grow, so at the time of pain in the heart, we feel the pain around the shoulder (Fig. 1).
We have to know that at the beginning stage of heart attack, the shoulder gets painful, especially the left shoulder close to the heart often gets painful (Fig. 2).
How to distinguish heart diseases from a shoulder joint problem
When you move your shoulder, if the pain gets worse, it is more likely to be caused by stiff neck and shoulders, and if the pain doesn’t change, it can be caused by heart diseases.
