[|AI|]  Hi, thanks for writing to Chat Doctor. Well, If I were your family physician for this case of a hard lump due to an injection, I would think about injecting into fat space or fascia or some thin vessel has been punctured!therefore you need to apply ice pack/cold compress with mild massage... Hope this answers your question. If you have additional questions or follow-up questions then please do not hesitate in writing to us. I will be happy to answer your questions. Wishing you good health.
