It sounds like you have some phantom/astral limbs anon! They may or may not be related to a kintype. (sometimes limbs like these are related to a hearttype, or other type of connection, or just happen randomly).
It took me a long time to figure out what exactly was happening with my own phantom sensations, so I definitively wish you well figuring it out. I think the first step would be figuring out exactly what you have and what they look like, and from there, if that means anything to you!
