I took boron in the past at 10mg and had some hot flashes, but it helped with my joints. So, I decided to try 3mg and it did help my wrists(mild arthritis), but ever so often, my testicles felt weird, like pulsating feeling. I didn't think much of it, until I started having pain. After figuring out it was probably the boron, I stopped taking it. That was 3 weeks ago and I'm still having pain. Anyone else have a problem like this? I have an appointment with the doctor next month, but trying to bump it up.
