This sounds like a partial obstruction perhaps caused, in part, by the salad. Although food alone is rarely the cause of an obstruction, if you already have narrowing present due to adhesions, scarring, stricture, etc, then high roughage foods such as salad can certainly have difficulty passing through the problem area, which can lead to a blockage. You seem to have the telltale signs - including watery stool.
I myself am prone to partial obstructions due to adhesions. I find that even after the blockage passes, I usually feel "off" for a few days. What you are describing doesn't sound out of the norm for a partial obstruction at all. It may have already passed, and you are just dealing with the residual symptoms now. You are doing the right things by sticking with fluids and avoiding solid food. Remember too that obstructions do cause swelling of the bowel so you are not going to feel "normal" immediately. I think many people are under the impression that they will feel instantly better as soon as they have a BM. While having BM certainly does relieve some of the pressure, your system has been put through the ringer and you have to take it easy for at least a couple of days.
But I would suggest that if you are not seeing an improvement within the next 24 hours, or if you still feel blocked, then you really should try to see your GI or surgeon, or failing that, go to the ER. Most partial blockages will pass on their own with fluids, walking, and heat applied to the area. But blockages that do not pass within about 24 hours can be serious, so it's not something to ignore. Certainly, if you start vomiting or develop a fever, you need to go to the hospital.
As to whether or not you have a kink, loops or a twist in the bowel, this is really impossible to diagnose unless you have imaging studies to confirm it. It may be worthwhile to call or email your GI and just report the symptoms you have had, even if you are feeling better now. Your doctor may want to document this and perhaps do some imaging later on to rule out a structural problem, especially if the obstructions start becoming more frequent.
