Hello and welcome to HCM,
All the symptoms that you have mentioned are suggestive of generalized body pains.
Stress is one of the common cause of generalized body aches.
First of all spot the stressor- it could be due to studies, peer pressure, or family issues.
If there is any kind of stress, manage the stress.
Stress can be managed easily by taking help of the family and friends.
Engaging yourself in some hobby like music, gardening, cooking, sports can help in relieving stress.
At the age of 16, these symptoms do not seem to have an organic origin.
They seem to have an psychological basis.
You can also take help your doctor and a counsellor.
Thanks and take care
Dr Shailja P Wahal
