Hello and Welcome to our family;
You are not alone and, I would say that, many of us can relate to almost everything that you've described. Every symptom that you've listed is familiar to us. Lupus is an auto-immune disease that can attack every single part of your body- organs, muscles, skeletal, brain, skin, tissues, joints, etc. So, it can be quite common for us to have the complaints that you've listed. Also, Lupus is a disease that changes - symptoms may get better, others may get worse, some may go away, new ones may appear.
Also, there are quite a few skin disorders in Lupus, they can be raised and red, smooth and itchy, bumpy and burning or combinations of all of the above. We all are very sensitive to sun exposure and doing so can almost always cause some symptoms to worsen or for the entire body to go into a flare-up (worsening of all symptoms). It is imperative that we avoid sun exposure as well as exposure to fluorescent lighting. So, we wear sunscreen (minimum 50 SPF) every day- indoors and out. We also wear protective clothing so that our bodies are not exposed to sun exposure. Sunglasses and hats are also a common apparel for all of us.
Debilitating fatigue is also a common symptom of Lupus and one of the most difficult ones for others to understand (many tend to label us as lazy). It is a form if "tired" than is indescribable to any one other than someone else who suffers from it.
One heinous thing about auto-immune diseases is that, once you have one of them - like Lupus - others want to join the party. You will find that most of us have overlapping diseases. I, myself, have Lupus, Raynaud's (fingers, toes, nose ect. get very cold, turn blue and sometimes hurts), Fibromyalgia (full body muscle pain with extreme fatigue), TMJ, IBS, and others. So, your symptoms could be from overlapping issues occurring simultaneously.
I do hope that you get some answers when you see your doctor. However, even if you don't, it is important that your symptoms be treated because another common feature of this disease is the fact that, if left untreated, it will most definitely get worse. It is a chronic disease and it IS NOT going away. You need to get treatment, take care of yourself, make some lifestyle changes and do all that you can to avoid allowing the disease to get worse.
I wish you the very best and I hope that you get some relief very soon.
Peace and Blessings
Look For The Good and Praise It!
