You may be intrigued by the concept or perhaps horrified at the idea of the process and all it entails, but if it's any consolation, offices will numb your skin with an ointment or ice beforehand (via Multiple Sclerosis Trust). In one session, you can expect injections that contain the venom or an actual bee placed on your skin to sting the area and provide "anti-inflammatory and pro-inflammatory compounds," which are said to help treat conditions (via Good Housekeeping).
Although its benefits haven't been proven, places like The Heal Hive, a center that educates and administers apitherapy, believes it has the potential to be quite effective. But if you're already aware that you have allergic reactions to bee stings, this is certainly not worth trying and can be life-threatening. If this isn't the case, and you're brave enough to face the stings, speak with a medical professional to see if it's a treatment worth pursuing (via Healthline).
