[|Human|] My 3yr old has complained about her shoulder and neck hurting when she woke up a few days ago. At first I thought she slept on it wrong and she wouldnt let me touch it. Last night after she fell asleep I felt a knot halfway between her shoulder and neck. Could this just be a pulled muscle and how could she do it in her sleep.
[|AI|]  Welcome to Chat Doctor .1. The location and consistency you have explained looks like brachial cleft cyst.2. Which is generally seen in that location and age.3. Lymph nodal mass in case of any infection / inflammation / systemic disease.4.However, better to see your doctor and get an ultrasound scan done, which will help in better understanding. Hope it helps you. Wish you a good health. Anything to ask ? Do not hesitate. Thank you.
