"I have been diagnosed with Sjögren’s and fibromyalgia. How do I know what symptoms are because of my Sjögren’s and which are from the fibromyalgia?
Should I change how I treat a symptom based on which disease caused it?"
There are many symptoms of Sjögren’s and fibromyalgia that overlap, and many people suffer from both conditions simultaneously, so this is a very good question. For example, both disorders can cause symptoms of dry eyes. If the dry eyes is due to Sjögren’s the person’s eyes will actually be dry, and artificial tears or medications to increase tearing can help. That same symptom seen in fibromyalgia is not due to the eye really being dry, but instead the nerves throughout the body being more sensitive, and feeling dryness when there is none.
Pain is another symptom that both disorders can cause. If it is from Sjögren’s the pain will typically be in the joints, whereas if it is due to fibromyalgia it can be anywhere, and will especially involve the trunk, muscles, etc.
Fatigue is a characteristic of both disorders as well, but it is difficult to differentiate the fatigue of Sjögren’s from that of fibromyalgia, except by “the company it keeps.” By this I mean that if you have overall symptoms of fibromyalgia (pain in many areas, sleep problems, sensitivity to brightness of lights, noises, odors, etc), then the fatigue you are experiencing is likely more due to the fibromyalgia, whereas if there are no other symptoms of fibromyalgia and you primarily are experiencing symptoms of Sjögren’s, then the fatigue is more likely due to the Sjögren’s.
