A few thoughts...
Well yesterday I went to go ride because I was done with barn chores early and would love to enjoy my horse. I tied him like I would normally and he started getting antsy
How long have you had him back, how much time have you spent with him since he's been back, to re-establish routines & ensure he's confident in his surrounds?
(Note 2). I was able to get them all clean and began to put the saddle pad on and he started kicking toward his stomach.
Who knows, could be due to ulcers, back pain, rough saddling & girthing....
and gave him wet grain when we got back.
I wouldn't be feeding the horse grain, wet or otherwise, as there are generally healthier alternatives, but please don't feed this or other high starch/sugar feed if you think he may have ulcers especially. I believe this sort of diet, &/or too little roughage is the biggest reason for horses getting ulcers & other gut problems.
out to the lounge line I go with this new problem.
I'd probably just address the problems rather than lunging him yet.
And where he is at now he is by himself for now. He does have ribs showing so I am switching feed to something more balanced verses the Tractor Supply sweet feed he was on.
So being alone again, he is likely to be more anxious generally can you acquire any company for him to help him be more happy & secure? Yes, sweet feed, being high sugar & generally also high grain, is definitely a potential problem.
to a point where he would manage weight and not flux weight.
So long as it's not to extreme levels, it's actually good for horses to 'flux' in their weigh, as you put it. Putting on more than ideal weight in 'good seasons' is OK, if there are regular 'bad seasons' to utilise the fat stores. It seems that a huge factor in horses developing IR & other metabolic issues is that many never get to use up those fat stores.
He is having BMís and eating.
He's eating barn managers??!
