###Human: My left nose makes a weird sound following a hit. Why? ###Assistant: Hello. Nasal trauma and consequent inflammation can cause symptoms like you are complaining. Epistaxis and stuffiness can be present. Since you have been examined at ER and they did not find any signs of fracture, there is nothing much to worry. The swelling you saw deep into your nose is turbinate, and they need not be necessarily identical on two sides. Since there was trauma, it is likely to be congested. There is no reason to be worried too much. Use decongestant drops for a while, and it will be fine.
