The smart way to be a self stinger, is to have an epipen somewhere in the house just in case. Always know where it is, and don't move it.
I've been self stinging for 7 years now. I believe I have put off knee surgery for that long. My doc said that the knee joint has a lot of bone there to deteriorate before surgery should be considered, so deal with the discomfort as long as you can.
I use a set of long tweezers and go out to the hive and carefully snag a bee right above her abdomen, I'm ready with my pant leg rolled up. Then, I gently place her bottom up to the skin on the inside of my knee, the stinger is barbed, so the skin will catch the stinger, you'll know when that happens. Then gently pull her away, place her in your and and thank her for helping your pain. Then place her back in the hive so her sisters can take care of her.
Or, there is a way to gather a few bees in a jar. I can give photos on how to do that. However, if you don't mind just getting stings along the way when in your hives, that's good too.
