Hi i am Dr Ahmed Aly thanks for using healthcaremagic site , I had gone through your question and understand your concerns .. In my opinion i dont think you should worry he may have touched a nerve usually the median nerve supplying your right hand which may make some nerve irritation and may take up to a week . some hot massaging and topical gels will be helpful and if the pain stayed for more than a week you may ask your physician for EEG ( electroencephalograph) for nerve conduction to exclude any nerve injury i dont think it is a critical injury and hope it subsides soon . Please click THANK YOU and consider a 5 star rating with some positive feedback if the information was helpful. Hope the above information helps you, Any further clarifications feel free to ask.
