Got vaccinated on the 3rd of June, the next 2 days were with typical symptoms, slight fever, major body and head ache. However the injection site was swollen and painful. Started icing it and the redness, swelling and pain subsided (took close to 8-9 days) However I can still feel a nodule, just below the injection site, it is painless but very much there. Will it go away on its own or should I consult someone? Thank you in advance for your help.
