Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern...
As per your complain you are suffering from
dry mouth and
dry eyes and along with it there seems to be generalized reduction in secretions..
As far as injections for VMD are concerned they seems to cause dryness of eyes but generalized reduction in secretions with hallmark features of dry eyes and dry mouth are seen in case of a syndrome known as Sjogrens Syndrome..
You should
consult a Rheumatologist and get evaluated..
As of now you can start supportive treatment like for dry mouth you can chew sugar free chewing gums as it stimulates saliva flow..
Artificial saliva agents known as Artificial Saliva Drops can be instilled in mouth many times a day for lubrication..
For dry eyes continue using artificial tear drops..
For dryness in nasal passage saline nasal sprays and steam inhalations and using a humidifier in your room can help.
Continue using stool softeners..
But for knowing the cause and getting long term relief complete evaluation is must..
Hope this information helps..
Thanks and regards..
Dr.Honey Nandwani Arora.
