Hello,
With history, it does not sound to me that it is
arthritis. So you can be relaxed for the same.
Now the cracking sound is actually the unlocking of the facet joints, which is once in while common for some.
But if it is always associated with relief of
back pain and
neck pain than its a
muscle weakness of the spinal column and an exercise will be of good choice to work behind it.
Headache can be
cervicogenic headache or due to stress as well. Since you are 15 and having no major traumatic injuries I do not think you will have any major symptoms. But you can get your eye checked once if anything related to the same.
Of course sleep is a must to look for, because if you do not sleep well, the body will enter the
fatigue state soon and may lead to muscle weakness leading to pain.
At the age of 15 doing regular physical aerobic exercises are recommended.
Because lack of exercise can cause pain and aches, and at the age of 15 its is hardly acceptable that one will have
headaches and back pains.
Hope I have answered your query. Let me know if I can assist you further.
Take care
