You know how painful it can be if you have been unfortunate enough to get cactus needles stuck in your skin. The good news is that you can do a few things to remove them. The first thing you should do is try to remove the needles with tweezers. If that doesn't work, you can try using tape. Place the sticky side of the tape over the area with the needles and then pull it off. This should help to remove some of the spines. If those methods don't work, you can try using a needle or a sharp knife to remove the needles. Be careful when doing this, as you don't want to injure yourself further. Once all the needles are out, you can wash the area with soap and water. Finally, if you have a lot of needles stuck in your skin, you might need to see a doctor. They will be able to safely remove the spines and help prevent infection.
