My son had a decompression surgery a week ago and some of his symptoms seem to have got worse. He had trouble be fore the surgery swolling which would then make him vomit, dizziness, headaches, sleep apnea and slured speech. Since his surgery his speech has got worse and he can barly swallow food without choking and vomiting. The doctors are going to put him on something for the dizziness but say everything else should get better in time. Has anyone else had this happen after surgery and if so did it get better?
