I recently received my first Myobloc injection after having received Botox for almost 5 years. Yesterday (about 12 days after injection) I started to have difficulty swallowing. Food feels like it is getting stuck and trying to drink at the same time, even water, can make it worse. Also, acid reflux started to the point of waking me all night. Has anyone else had similar experiences, and if so, what did you do to cope with them?? It is so embarassing to be eating dinner with co-workers and all of a sudden you can't swallow food.
