Hi J.,
Growing doesnt cause pain. If it did, then babies would be crying nonstop while they grow more during the first year of life than any other time in their life.
Growth occurs during sleep. That is why babies sleep so much also.
Anytime you have persistent pain in the joints you should suspect adrenal disease. Especially knees, hips, low back, and also pain in the leg muscles, ankles, toes.
My dd was diagnosed with growing pains at 4-12 because they DIDNT KNOW what it was. That is a catch-all phrase that they get away with that is bogus. Ive done enough research to be a doctor myself- and i have found out that my daughter has adrenal disease (Addisons.) There is also cushings disease, which also causes joint and muscle pain.
Both of these syndromes are very common, (even though the net says they are not) both have lots of symptoms so do look them up on several different sites to get a full picture. Further, anytime there are growing issues (too big for age or too small for age) the endocrine system and adrenal gland should be looked at also.
A SALIVA cortisol test should be asked for. If you can't get it through a doc, you can order it on canaryclub.org through ZRT labs.
As you can see doctors dont want to help find problems, so even getting this test deciphered will be a pain. Even experienced endocrinolgists don't know what the heck is going on half the time. You are going to have to become your son's advocate and do your own medical research. There are adrenal supports groups on yahoo groups.com that can help you navigate the medical results.
