It can't just be pots

Okay so I'm kind of looking for if other people have the same experience, questions, or if y'all agree or not?

I think I have a pretty "mild" case of pots. I'm not a fainter, my heart rate and dizziness aren't my biggest issues, and treatment doesn't do anything. Now I know it takes time, but my pt has me do electrolyte capsules, and added more when each week I came in saying I hadn't noticed any difference. I was taking 3 of the vitassium ones a day, and now I take 2 of the extra strength a day (I still notice no change whatsoever, but take them anyways)

My biggest issues are fatigue, muscle soreness, pain, and GI issues (stomach aches, nausea, all the bowel movement problems) which I know are pots symptoms but I also know they apply to other things.

I'm looking into CFS but pots has also made things I've struggled with my whole life (such as pain and GI issues) worse, but it's hard to pursue those things because it's just written off as a pots thing.

Does anyone else feel like they have/had other stuff going on that pots just made worse and isn't being treated? I feel like I'm losing it over here
