After weighing the pros and cons, I have made an executive decision that I'm going to start knitting again! Yay! Just a little bit, like maybe 3 half hour sessions a week or something like that. I honestly don't think that small amount of knitting is going to adversely effect the cyst on my hand and I know that it is going to vastly improve my quality of life to be able to knit again, so... I'm doin' it!!
Also, an update on my hand: I am going in for a consult with a hand surgeon in the first week of March to get it checked out. I'm really hoping an actual surgery isn't required to fix this, but, either way, I will just be happy to get it over with!
