No 2 people with lupus of any type will have the same symptoms, nor will a lupus patient feel the same way on every day or every week. It depends on what part of your body is affected, what type of lupus you have plus the general state of your health at the time. If for instance, you have a really bad cold or flu, then if you are having a flare it will last longer and make you feel very unwell.
Frequent flares though should be discussed with your doctor, as the treatment regime may need looking into and then changing. Looking after yourself as has been said, i.e. trying to relieve stress and not putting yoursel into any situations that cause this to the best of your ability. Other things are keeping out of the sun, pacing yourself when feeling unwell. When you are well, you still need to pace yourself and not overdo things just because you are feeling better that day. Eating good food, no special diet but healthy eating - this type of caring for yourself will help reduce the severity also.
Hope this is of help to you. Take care.
