Trying use the lidocaine just for flares, or if you experience an injury to another area. I feel the cream is stronger initially, but the patches work better. I find they lose effectiveness if worn more than once or twice a week. It's a good thing to have as an option, but is not helpful to rely on daily,IMO. Test how what works best for you!

This link state's Capsacin isn't proven to be effective for RSD, though some claim they experience a reduction of pain if it's used consistently (it's supposed to lower substance p).
