Hi and welcome to HCM. Thank you for your query.
Thre are certain neurologic complication of variccella virus and it should be considered in your case so I advice to visit neurologist
for further testing because corticosteroid therpay may be necessary. In most cases this is temporary and not serious. There can be disorders of inner ear
or viral encephalitis
so you need to do some tests if symptoms persist.
Wish you good health. Regards
