stuck between sore throat and shoulder pain

I've been taking Colloidal Silver to get rid of a sore throat and it was working very nicely, until my shoulder started hurting. So I stopped taking the silver to give my shoulder a rest. 24 hours later, the shoulder pain was just about gone, but the sore throat was back. I took another dose of silver, the sore throat pain eased up, but my shoulder started hurting again. Weird. If it isn't one thing, it's something else. Guess I will have to switch to oregano oil to get rid of the sore throat.
