Hi Numb, how are you. Just wanted to see if I could help. I am sure the puffy face could be from so many things. Sinus infection etc. But I have it pretty severely now especially on the left side where i also experience numbness, tinglling, a heaviness. My doctor has but me on a diruetic heart medicine. This was done when i moved in to the lesion stage of rsd. I did find the reason once for perscribing this med. it reduces the collection of fluid around the heart and brain as well. It helps contol my face swellling as well.Its abbreviation is HCL. I will do some research and post more for you. Mine is rsd related. But again, it can be caused by so many things. Sorry this is not more helpful - but i will find the inforamtion and the correct name of this med for you. Take care, cz
Im back... I found the information:


Hydrochlorothiazide, sometimes abbreviated HCT, HCTZ, or HZT is a popular diuretic drug of the thiazide class that acts by inhibiting the kidneys' ability to retain water. This reduces the volume of the blood, decreasing blood return to the heart and thus cardiac output and, by other mechanisms, is believed to lower peripheral vascular resistance. Hydrochlorothiazide is sold both as a generic drug and under a large number of brand names, including: Apo-Hydro, Aquazide H, Dichlotride, Hydrodiuril, HydroSaluric, Microzide, Oretic.
