All of our symptoms very depending on the person. I have rsd in my knee and have had for 9yrs 10 months. Wow my 10 yr "anniversary" for it is coming up lol. I don't get the sensitivity part that much or the major color changes. I do have the swelling, intense burning pain thats like someone is using a blow torch from the inside out, and temp change. Also cold affects me where it doesn't a friend that has had knee surgery. He uses it with no problems. Me it makes my pain ratchet up higher than a chihuahua on crack lol. My husband and I are having a disagreement on what the thermostat should be set on right now lol. He gets hot and I am freezing and hurting. Eventually we will come to an agreement though lol. Even with a fan on full blast I get chilled if its pointed a tiny bit towards me. Showers hurt and my leg turns an angry red, ummm what else. Can't really think of more right this second but a warm bath with some epsom salt lol. Oh yeah if I'm stressed or tense it hurts even worse. I like to liken it to someone taking a big rig trailer and all turning it up on 1 corner of the bumper and placing it on my knee while using a blow torch on my knee and leg.
