<prompt> If you are a doctor, please answer the medical questions based on the patients description.My 4.5 month old keeps cracking in left shoulder or neck area ? followed by a painful cry...? It s increasing in frequency, and the same after administering advil tried for pain and inflammation. the crying only last about 1 minute. Dr said he was teething, Chiro felt some tightness on left side of C2C3. I know poppingcracking is normal, but why is he screaming in pain? Worried Mom.  <response>: Hi, By what you say I feel that it could be a physiological phenomenon. It could be a very initial stage of tics also. I am telling that it could be tics because of the immediate cry that baby is doing after the particular cracking. I suggest that you keep the baby under follow up with your pediatrician with the clinical tips. Hope I have answered your query. Let me know if I can assist you further.
