“EmerAid saved Penny with megaesophagus”
Penny always struggled with weight gain and lack of nutrition because of her megaesophagus. We even had to make an appointment to put her down because she was in such bad shape. Thanks to EmerAid, she’s now way better, and I’m so unbelievably grateful that I didn’t go through with it. Thank you so much!
