Hi, I m a 17 yrold female who has chronic gastrointestinal issues, (gastroparesis and collagenous gastritis) recently I have been experiencing some new strange symptoms Immediately after I eat I get extremely shaky, in my hands and my right hand is much worse, and sudden onset of fatigue and stomach pain. My knees also feel weak during this; these symptoms go away but return as soon as I have eaten again, it also doesn t matter how soon or how long its been since I ve eaten
