Hope everyone had a happy new year. My rheumatoligist added plaquanil to my medication. While this pill has helped my pain quite a bit, I have been catching every cold out there. I did start a position as a substitute paraprofessional at my kids school so I am around germs all day. On top of getting colds, I have this strange symptom. It is hard to describe. I get it mostly in my right arm. It almost feels like a vibration through the entire arm but kind of painful. Not extreme pain. It happens if I have an itch and scratch it and sometimes if I type of use my right hand to hold the phone. It is very weird and only lasts a few seconds. Anyone experience anything like this?
