Namechanged for this as outing to anyone who knows me.
I think the problem you are facing is that Sjorgrens seems to be a poorly understood and minimised condition, even amongst the medical profession.
You may have Sjorgrens with those symptoms, but typically the dianosis takes years (three years for me). Even then I am often challenged when I explain how seriously some of the symptoms are impacting me.
My Rheumatologist is OK, but always goes straight to drugs when new symptoms appear, rather than discussing other options or ever explaining how this condition has arisen and the full gamut of symptoms to look out for. As I understand it the Drugs he offers will relieve individual symptoms but not stop progress.
My GP on the other hand is amazing. She diagnosed it in the first place, understands my desire not to drown in drugs (all with their own side effects), provides a battery of topical treatments for my eyes, mouth etc and helps me understand what I am dealing with.
My other sources are the internet and a couple of support groups. One on FB (Sjorgrens Support), one on Healthunlocked.
Although I am cautious about support groups I have learned a lot, about the nature of the condition, how it flares and presents. Most of all I have come to understand the true extent of the minimisation that goes on in the medical profession around this condition. I don’t think that is deliberate, just that it is poorly understood.
I now know that what I am experiencing as serious symptoms during a flare is not ‘all in my head’
Three years on my Sjorgrens is fairly well controlled. I use Eye drops during the day and stronger ones at night. I have mouth drops for when things are bad. I use SVR lotions / creams to deal with my skin issues and a controlled Gluten, Sugar and Dairy free diet to deal with the stomach & gut issues. I would say it is the diet that is the most beneficial. If I stray, I often trigger a flare.
My advise would be to arm yourself with as much information as possible and challenge your Rheumatologist to explain full what is going on, the full range of symptoms you may experience and how you can obtain relief.
If he cant or wont, ask your GP for support in having you referred to someone who specialises in this area. I have read that Dr Elizabeth Price in Swindon is very good.
