Thank you for placing your query on Health Care Magic
Since you have taken all the necessary vaccines, you need not worry about anything serious. However some times few superficial nerves get entangled in the forming scar and they give a funny sensation long after. First thing is to notice is whether it is well localised to that scar or is a bit generalised. Generalised pain may indicate some vitamin or essential micronutrient
deficiencies. That can be resolved with thiamine
) taken orally. If its truly localised then you need to decide whether its tolerable or not. If its mild, you can ignore it and it will resolve itself (though it may take a long time). However if its severe then you may consult a pain specialist.
Hope that helps
God bless you
