Help first time mommy with throat problems !!!

Miranda
This is my first pregnancy as I mentioned on the last post.. well, about 3 1/2 weeks ago to a month ago my throat started acting up I can't swallow anything, sometimes it's sore and feel stretched and other days it fine. I went to the doctor because when I eat I have a chili mg sensation that reccomemds endoscopy treatmemt , maybe displaying surgery which they said is safe inn the pregnancy. Now since I'm not able to eat anything I have been eating liquid soups and drinking boost nutritional drink which has 26 vitimans and minerals , 14g protein , 3g in fiber, and calcium and vitiman d to support bone health , it has 35% calcium , 100% vitamin E, 25% folic acid ,25% vitamin A , 35% iron, 40% vitimans K, 35% vitamin B12 , 30% zinc, 100% vitamin C, 60% vitamin D , 35% vitamin b6 , 25% biotin amd I was wondering if anyone else has ever had my problem and has to live off drinking them till your first obgyn appointment ? Or if they are healthy and okay to live off of for the baby's nutrients until the first appointment , I'm trying to give my baby all the nutrients he or she needs , helppppp????
