My son has been dealing with a cold for about 3 months now, and I'm really worried about why it's not getting better. Even after trying different medicines, nothing seems to work. We finally saw a homeopathic doctor, and they mentioned it could be due to adenoids. Ive never heard of adenoids beforecan you explain what they are and how they might be causing these cold symptoms? Is there a reliable way to treat this issue? I'm just looking for some guidance on what to do next.
