Don’t worry about it, just rest, and recover,
You will heal from a herniated disc, C7, I am in the spine industry and didn’t even know we had that many disc in the neck,
Better up there than in the mid or lower back.
You are losing mostly water, do your pct, do hcg, or
Clomid or both, help maintain gains.
You should be given a decent neck brace post surgery, if the even operated, once you have that and you have given it a couple of weeks, you can get back in the gym, seriously, lightly,
When the pain subsides you can with bracing go back.
PS, the sleeping is natural after injury and cycle.
Good luck you will be back.
