Hi! Welcome to Healthcaremagic. Thanks for sharing your concerns with us. We will try to help you in best way possible. First of all it s sad to know what you had been going through lately. Based on the history you have shared, if it is accompanied by a rash or skin lesions than dermatologist is the right person to be reviewed and herpes or nerve dermatomes involvement needs to be ruled out. A neurologist opinion or involvement of nerves and nerve conduction studies to see functional issues should be done. May also be sequence of that whiplash injury that you had experienced. For itching anti histamines like cetrizine or loratidine can be helpful. Otherwise nerve pain suppressants like gabapentin or duloxetine may be helpful. Wishing you a speedy recovery. Regards
