Anyone here with medication induced RLS? I think I have developed it but i have no idea which medication I take is causing it.

All of the doctor's appointments I've had to make lately are getting expensive, so I'm frustrated. I have a bad shoulder, back spasm issues, and my joints are feeling slightly swollen. If I could figure it all out on my own through trial and error of taking vitamins or changing my diet or something, that would be preferable.

I've looked up tingling sensations in legs and arms (plus my other symptoms), and I've narrowed it down to these possibilities:

1. Iron deficiency (I'm a vegetarian)
2. Vitamin D deficiency (has been low in my blood work before)
3. Diabetes (please God, NOOOO!!!)
4. RLS from medication

YES, I will see my doctor before things get worse, but I'm just curious if there is one of my meds that is more likely to cause RLS than others.

Thanks!!!!
