I have read your question and understand your concerns. Paresthesia points to symptoms, the probable condition that may cause such issues is occipital neuralgia that is linked to the upper cervical nerves who may be pinched or compressed. Yes, you should mention these issues to your Doctor since you are going for check up. Your Doctor may undertake other steps to diagnose you correctly. Hope I have answered your query.
