[|Human|] I got a flu shot on Wednesday and yesterday I noticed a quarter-sized red spot a few inches below the injection site. It is warm to the touch. It is now about the size of a tennis ball. I dont have any pain, but the site itches sometimes. Is this normal?
[|AI|]  Hi. Welcome to Chat Doctor . I have gone through your query and can understand your concern. As per your complaint a quarter sized lump a few inches below the injection site can be due to allergic reaction to the medication injected while it can also be unrelated to the injection and can be due to any bug bite or insect bite. I would suggest you to take anti-allergics like Ben Chat Doctor. . In case if it does not resolve in a week consult an Allergist and get evaluated and treatment can be planned accordingly. Hope this information helps. Thanks and regards.
