What Causes Intermittent Electrical Shock Sensations In Right Upper Chest Area?
Possible irritated nerve.
Detailed Answer:
Hello and thanks for using HCM.
I have read your question and understand your concerns.
Electric sensation in an area of body under the skin is a symptom mainly related to abnormally charged nerve(s) and/or muscles, or it can be related to pinched nerve too.
It is not a common symptom of all health issues you mentioned.
It is important to know if the port you refer contains any electronic device, that can be responsible to intermittent electric charges around it, triggered by movement.
A pinched nerve by the port/device also is one possible explanation of your concerns.
In all cases a port revision is needed to understand better the cause of your symptoms, and, if any abnormal movement is noticed, re positioning is needed.
Hope you found the answer helpful.
Let me know if I can assist you further.
Greetings.
