Hi all. With my PA, I've been taking weekly injections which have worked ok. I recently started on daily sublinguals because I could feel symptoms returning a few days before I was due for a shot. I decided to use the b12 sublinguals(2500 mcg) and do my shot every 10 days. So far this combo is working much better and eliminating up and downs with symptoms. Also I wanted to ask again about PA and stomach issues. I've been really sick for over a month with constant stomach pain and now passing blood. I'm being set up to see a GI specialist and an oncologist because I have an elevated lymp absolute as well. Has anyone else had extremely high instrinic factor, stomach pain, polyps, stomach cancer from PA?
