Normal To Have White Discharge Under Tongue In Patient With Sialadenitis?

Hi if I have sialadenitis would a white substance come out of the gland duct under the tongue when light pressure applied? I have been suffering with this for several years and dr always gives anti biotic and steroids which help but its always back as soon as tablets are finished within a couple days. I can actually feel the substance as it struggles to leave the duct and its painful. Iv has scans etc and the ent dr says its not stones and is at a loss to why I constantly produce this white stuff. when it come out its just creamy not hard which seems strange as its so painful as it travels to the opening. once its cleared its better til it builds up again. usually worse in mornings. I have to put ice packs on my neck to encourage the white stuff to leave and the cold seems to help it come out for some reason. I am at my wits end bearing this for so long and am considering gland removal but ent says as far as he is concerned no one will remove a healthy looking gland. (it cant be that healthy with all the pain and suffering its causing me. I am possibly having a food intolerance test as next step in case something is making produce this substance!!! its expensive tho. any help u can advise is most appreciated Kim
