There is tingling and bleeding under the nails.

When you say that your fingernails are more painful than the day before, you start to get infected and inflamed, but it's normal for a wound to get infected and inflamed. It's no big deal, especially for such a small wound.

When you see a thorn, you should pick it out. You can't let it stay overnight. Before using the needle, you need to soak the needle tip in iodine or alcohol or highly alcoholic liquor for a few seconds. Don't just pick. If there is nothing at home, you can burn the needle tip with a lighter for two seconds to disinfect it.

If you can't pick it out yourself, ask someone to help you. Be patient.

In fact, it is not necessarily a thorn left in the meat, but it may just be a small wound. You'd better make sure

However, if you really can't get it out, don't worry too much. It's normal to have thorns in life. If you can't get it out, forget it. Humans have been on the earth for tens of thousands of years, and there are many thorns. The body has long evolved a corresponding coping mechanism, and you won't die or be disabled if you prick a small thorn. For example, small thorns in meat may cause slight suppuration and will naturally discharge pus.
