I have ALWAYS itched when on hydro- when I take enough to knock out the pain- though, again, it starts with my nose

When I upped the dose I was taking, I started itching on my nose, then my legs, then my chest- just weird stuff. My boyfriend at the time did some research and found that's a normal vascular reaction when you take a high dose of hydro. However, not knowing if you've upped your dose recently, I couldn't say- but wouldn't that be a nice relief to know? Anyhow, hope you don't have shingles, I've also heard that appears rash-like and can become very painful. Best of luck!
