Thanks for your question on Healthcare Magic.
I can understand your concern.
Yes, all these symptoms are related.
In teenagers, undiagnosed
stress and
anxiety are very common.
And these can cause multiple pains at head, neck, shoulder along with
chest tightness.
So better to
consult psychiatrist and get done
counselling sessions.
Try to identify stressor in your life and start working on its solution.
You will also need anxiolytic drugs.
Calcium and vitamin d 3 supplements are also beneficial for multiple pains.
Don't worry, you will be alright with all these.
Avoid stress and tension, be relax and calm.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
