I can understand your frustration, even though I have not had an injury quite like that, I did break my arm last year and it was a huge damper on my physical activity! it really sucked because I knew it wasn't worth it to work out and hurt something else trying to make up for the lost homeostasis ...
It seems like this is a pretty complicated issue and that a lot of things can agrivate it and make it worse.
I guess my advice is to do what you know you can do without pain because if you start doing MORE you are going to get yourself into a position you may not want to be

(like, ****, why did I do that haha) I would also say, and it's so hard to say

this because it seems like you are very into

out and I am too... to just take a nice break.
Yes, I understand 3-6 weeks is a long time!!!

but I think it would be worth it if you end up feeling 100% better rather than trying to workout feeling like crap! !
Just make sure you eat good! take this 3-6 weeks to tune up your nutrition and make sure you are getting all of your vitamins/minerals/drinking water ect --to actually get back to your original question...exercising and eating go hand in hand when trying to maintain weight so if you are eating more but not exercising you are obviously going to gain weight. You know what though? even if you did gain a pound, I am sure you have the motivation to get right back into it when you are fully recovered! otherwise, eat your fruits and veggies, stay away from high sugary foods...
Hope you feel better soon!!!!
