[|AI|]  Hi. Welcome to Chat Doctor . I have gone through your query and can understand your concerns. As per your complaint as you were given injection for upper left qua Chat Doctor. . It is although not commonly anything fatal but TH swelling can last longer. As you said that still some swelling is left it means that some swelling has subsided, so it is a good sign and need not worry. I would suggest you to do alternate warm and cool compresses over the swelling. Gradually the swelling will subside, and you will be completely alright. Hope this information helps. Thanks and regards.
