Ow - Like the others I had horrible reflux. Aciphlex (sp?) was prescribed and worked wonders.
I get wicked heartburn on Solumedrol, and keep a bottle of antacids both in my home and in the car.
I hope you feel better, soon.
I have monthly injections and I also have never had this issue, but people have different reactions.
I take it twice monthly and have never had an upset tummy. Let's hope it is a fluke. I do retain a lot of water after treatment and my mouth gets dry. I know to just keep on keeping on drinking those fluids. It passes in a few days.
