Throat/esophagus pain, discomfort after switching masks types? From full face to nasal pillows for me

Has anyone else experienced throat pain, trouble swallowing or discomfort in the esophagus after switching mask types? I went from a full face mask to ResMed P30i nasal pillow mask, and the first few nights were really good, great seal and scores of 100 each night, but then I started developing a sore throat. I'm not sure if it's from the new CPAP or just a sickness, but I noticed the air would be forced into my nose, but sometimes leak into my mouth and out of my mouth tape. I woke up with a sore throat a few times, and over the last week I've had issues swallowing, a feeling of a lump in my throat or feeling like there's excess mucus in my throat. I started taking some allergy medicine as recommended by a doctor from a virtual InstaCare visit. They didn't see any swelling in my throat or tonsils, (had me point my camera down my throat with a flashlight) and I haven't had trouble breathing but I've gotten pretty close to it, I've had trouble swallowing and a few times that I feel like I'm going to choke on my own saliva. Wondering what experience others have had when they switch CPAP masks and if that caused any throat pain or issues, and what your solutions were
