The withdrawal (w/d) from suboxone takes a little longer, since suboxone is a longer acting opiate.
I'd mention the leg pain to my doctor. However, all-in-all you don't sound too bad off. I also did a 5 day taper in a outpatient detox program. I was grateful that the w/d wasn't any worse than it might have been. Cold turkey w/d from oxyxodone or hydrocodone were ridiculously difficult.
I worked hard not to allow w/d anxiety and pain "make me" want to use.
And for me the w/d was exceptionally small compared to what active addiction caused me in pain, anxiety and much more.
