I have a chapter where disaster befalls the MC and they are knocked unconscious. The next chapter is a switch in POV, showing the MCs rescue. It ends with the MC still unconscious but safe. The next chapter has the MC back in action 100%.
I feel that I need a transition. I wrote a "recovery and reconciliation" chapter but I felt it bogged down the pace. I have the following ideas I'd like to bounce off:
1. Make allusions to the recovery while showing MC at 100%.
2. Have a really short "recovery and reconciliation" chapter that slows the pace, but only for a little bit.
3. Have a longer transition chapter and make the chapter interesting by adding backstory.
Well, I don't know what level of damage your MC received, because it is not the same if they only hit him in the head, they broke his leg or even he received a bullet. In fact, I am going through a similar situation in which my MC was removed from the scene by sleeping with a drug in his drink and then subjected to a Matrix effect with the purpose of hallucinating so much as if he were in a dream, and finally forget what he were in or what he were about to discover.
But, going back to your case, I would forget about the recovery chapter and start the next chapter with the always effective phrase: A month later (or a year, a week, whatever you need depending on the situation). That, in my opinion, allows you to put a gun in your MC's hand again and here we go again, with the advantage that the reader will swallow it, he will not be arguing: well, what happened to he being out of combat? and all that. At most you can explain in a couple of paragraphs that the recovery was such and such, that he took advantage of hooking up with a nurse (or the doc, assuming your MC is a girl, right?), and voila, you can move on with history and you will not deviate.
You can also start with a cliffhanger, like: Well, there was the very wicked bad man, and the good boy was spying on him above the container, and he was going to jump on him, etc, but wait, and there you fit the explanatory paragraphs like:
Those weeks spent with one leg up were a drag, have you noticed that in hospitals (assuming) they always serve that tasteless pudding and that awful rice? And I don't even tell you when I had to go to the bathroom, what would I have given to have a beer, etc, etc. Damn, he couldn't even watch the national team game, blablabla.
Because the other idea, that of putting in a backstory, really worries me.
I mean, it already happened to me. Well, given the hallucinating thing in which my poor MC begins to think that he is dreaming because at no time can he know exactly where he is or what is really happening, and further the doctor (a woman in secret belonging to a rapid deployment regiment) has forbid him to say specific names or any something that helps the AIs to locate him and at the same time find out what he was about to find out, they are quite intrusive little robots, the point is that little theme of the backstory has already made me write 100 pages, that's why I tell you don't even think about it, because it's the quickest way to fall head first into a loop.
This is what I can think of to advise you for now, I hope it helps you.
