3 years remission and on zepbound for weight loss

Well my ldh has been hovering around 174 for 3 years, and after an ER visit due to side affects (extreme lightheadness)from zepbound my ldh was 294. I asked for the test because they were running all kinds of blood tests for my heart. Including 2 images of my heart and lungs, All came back normal. Now I'm scared because my ldh jumped to 294. I have my 6 month follow up today but the last 2 days I have been so worried and all the cancer related journey I went through flashed through my head.
