Hi. No, that's not normal. Are you coming down with the flu? Talk to your parents about a physical or get one yourself if you handle your own health care now.
Researchers aren't sure why cold weather can cause joint pain but one theory, based on a small study, is that inflamed joints swell as barometric pressure drops and
the swelling irritates the nerves around the joints, causing pain.
You could try a warm bath with magnesium flakes to help with the pain. Also maybe apply arnica or capsaicin cream to your sore joints. Also considering taking omega 3 supplements to help reduce inflammation and avoid inflammatory oils high in omega 6 (soy, sunflower, corn, cottonseed, safflower, vegetable oils).
