Hello! First of all, I wish your mother a speedy recovery! For your filial piety, I tell you, this is what people often say, "hyperosteogeny." The so-called "hyperosteogeny" is commonly known as bone spur.

You should know that any bone spur can't be removed by injection and medicine. "It's a three-point poison." There is only surgery, but the effect of surgery is unpredictable. Even if you are lucky enough to achieve your goal, it will grow back tenaciously with the growth of years. This is the "annual ring" of the years of life, irreversible! In addition to the suggestions given by the above members, I would also like to introduce several remedial measures to you:

1), aim at the painful part with a household hair dryer and blow it with hot air for about 20 minutes, which can relieve or alleviate the pain.

2) Buy 2 Jin of salt, stir-fry it in an iron pan on the fire, and wrap it in a cloth bag for local hot compress, which can also achieve the purpose of relieving or alleviating pain.

3) It should be noted that in order to prevent edema, you must not rub it hard to avoid more unsatisfactory edema symptoms.

If you are satisfied with the above answer, please don't live up to my kindness and click "adopt as the answer" in time.
