Question
Last summer, after receiving a vaccine, I developed a hard lump on my arm. I asked the vaccine injector, who said the lump would disappear on its own. However, a year has passed, and the lump is still there. The treatments and effects I have undergone include: my doctor recommended using hot water compresses for a month, but the situation has not improved. I hope to get help with whether surgery is needed or if there are other solutions?
Answer
A hard lump on the arm after receiving a vaccine should be cared for properly, kept dry, and a light diet should be followed. You can apply a cold compress appropriately, and the lump will gradually disappear. If the lump still exists after a year, it should be checked for infection or inflammation, and if necessary, drainage treatment should be performed. These are the suggestions for the question “What’s happening with the hard lump on my arm after receiving the vaccine,” hoping it can help you. Wishing you good health.
