Possibly: Sudafed is pseudoephedrine, which has some similar activities on the parasympathetic (involuntary) nervous system; it may increase the pulse, increase blood pressure (usually at higher doses than 30mg); it's possible that in some people it may increase peristaltic movements of the bowel muscles, and thereby cause some bloating and a sensation of tightness.
