Well 2 weeks and it is so true that the healing process takes time. Taking high dose lansaprazole because of problems swallowing and pain in between my shoulder blades,heart beat all over the place. I said in my last post I would say 'do it' well some days yes and today feeling the strain. Has anyone else had constant belching and pain on swallowing? Also slow heart beat and extra beats? Have spoken to specialist nurse and apparently this is all 'normal'.
