A study in the purpose of pain assessment in neonates and relief of pain cycles; not only for ethical view but also because repeated painful exposures can cause deleterious consequences. Gathered information from various medical references and previous studies discussing pain physiology, modulation and pain calibration instruments all are provided for this purpose. In Egypt, pain in neonates is underestimated and it's prevalent among the public that circumcision is preferably carried out in the first week. And from this point, we were determined to make this study about pain in neonatal age.
