Well my personal experience a few days ago says this totally does work. For the first time ever this spring I have been feeding bees around my house. I made a few wooden feeders that they love. Anyway I have allowed them to crawl all over me unrestricted. And they send the scouts to come seek me out whenever the feeder runs dry. In a short period of time I have concluded that they have some special powers.
Two days ago for the first time ever one lightly stung me while I was feeding them. Somewhere right under or behind my right ear. I haven't been able to find a mark. But I had an instant reaction with good dose of pain.
Nevertheless, the next morning while on the pot it struck me. The fact that my right jaw was sore and my right ear wasn't ringing nearly as loud as normal. In fact, I couldn't tell if the ringing wasn't gone entirely due to the left bleeding over. But perhaps it could be gone. All of which tossed me into instant tears of joy right there once I realised the connection between the sting and the vastly reduced ringing.
These little creatures are really something else. Today I'm noticing that for whatever reason they seem to be keying on my right ear. I'm still searching for the sting mark which stunningly was made with surgical precision. I'm now debating holding one and forcing it to sting my left ear as well.
This is quite remarkable to say the least. I've watched them work on each others various physical issues. But to figure out mine and repair them is amazing! These little creatures are on a much higher order than I ever thought.
