why does my shoulder feel uncomfortable and my nipple tingles when its not cold
There could be a few reasons for this discomfort and tingling sensation. One possibility is that you are experiencing nerve compression or irritation in your shoulder, which can cause referred sensations in other parts of your body, such as your nipple. Another possibility is that you may have a musculoskeletal issue in your shoulder that is causing referred pain. It is also possible that hormonal changes or imbalances in your body could be causing these symptoms.
It is important to see a healthcare professional to determine the cause of your discomfort and tingling sensation and to receive proper treatment.
