My wife was diagnosed with PBP last month. She had a lumbar puncture / spinal tap to rule out a long shot problem. She has had continous nausea for almost three weeks post proceedure. She seems to have a mild case of GERD. At this point I don't know if the nausea is PBP related. The nausea and excess saliva, on and off for some months, is having a terrible impact on her mental health, as if she needed anything more. Has anyone heard of this symptom related to PBP?
