I have this disease since 15 years now. For about 3 weeks, i have a little bit of saliva coming from my throats, and i also have arm and leg pain, also i am loosing a lot of weight. So i wanna make sure, if these are symptoms of Pneumonia??? Help will be appreciated.  <response>: Hi welcome to Chat Doctor... Just increased salivation doesnt suggest pneumonia ... The presentation in pneumonia is in the form of...-chest pain -fever -cough -dyspnea For its diagnosis auscultation and chest x-ray needs to be done ...X-ray will show opacity in form of consolidation or interstitial infiltrate if pneumonia there . Continue treatment for Parkinson disease ... Take care ... Advise : Physician consultation for examination...
