Can call Dr on video: COVID-19 pandemic at this time so a doctor may wish to consult by video first instead of an in-person visit. Such symptoms can be from a strep throat, influenza, other inflammation or infection, a drug side effect, etc... Usually, a person calls the doctor if the symptoms are moderate or worrisome, to discuss and plan next steps. It is likely the cause is something other than a flu shot. (3/31/20)

Flu Shot symptoms: While most patients have either no symptoms or just mild muscle soreness at the injection site after the flu shot, occasionally patients do have mild to moderate but brief systemic symptoms that resolve in a day or so. This is probably the reaction of your immune system to the immunization with flu antigen. It is not serious and many patients take a little acetaminophen or ibuprofen for relief.

Could be the jab: Influenza immunization (the "flu jab") can sometimes produce symptoms, including soreness and aches. Unlucky people actually get the flu (coincidentally) within the week or so after getting it, because it is not immediately or 100% effective. Some stories of immunization actually causing the flu are probably due to people not realizing that they already have the flu as they get the immunization.
