U is for unique.
Symptoms of lupus are unique to each person. There is no pattern. Some things can happen in all lupus patients, but not necessarily at the same time. And they symptoms mimic other diseases, making it harder to diagnose. It mimics fibromyalgia for one. The person with lupus can be suffering great pain, with no determined cause.
Because all symptoms are unique, all treatment is unique. Some people with lupus take the same drugs. Others take different drugs. It all depends on what your symptoms are and how you react to the medications.
Some lupus patients reject the meds given, which is another uniqueness. Others tolerate the meds well.
We shall see which one I am going to be.
