Welcome to the forum.:welcome:
Do your parents know about the health problems you are having? Are they supportive of you getting to the bottom of them? It would really help you if they can help you with doctors appointments and in planning what you discuss with the doctors.
Doctors generally divide 'symptoms' into two sorts - objective and subjective.
Subjective symptoms are things that you describe you feel, so pain, nausea, fatigue etc.
Objective symptoms are things that someone else can see or measure, so blood tests, rashes, joint swelling etc.
When a doctor is trying to diagnose, they will need to look for both sybjective and objective symptoms. So, you need to tell the docotr what you are feeling, but they also need to do tests. They will need to take blood from you, to look at your joints and skin, listen to your heart and lungs, measure blood pressure and to test your urine. On the basis of what is found (the big picture) they may be able to make a diagnosis.
For most people with lupus, it takes a while for there to be enough evidence to convince a doctor that the problem is definately lupus. You also need to be seeing a doctor who is a specialist is diagnosing lupus. These are rheumatologists: and some rheumatologists are better at diagnosing lupus than others.
Where do you live? Do you think you and your parents could convince your family doctor or paediatrician to refer you to a rheumatologist?
You wrote that you have kidney problems. What were they? Do you know the results of tests you had? Lupus can cause a specific problem caused nephritis. This is inflamation in the kidney, not caused by infection but by the immune system attacking the tissue in the kidney. Usually someone with lupus nephritis doesn't have symptoms early on and the first problem found is protein in the urine.
What other symptoms are you having that you suspect might be lupus (asside from the joint pain, heart pain and fatigue?). You've probably already read through information about lupus. The info at the home page of this site is pretty good. Read through it and make a list of the symptoms that you have, especially if there are things that can be objectively measured like abnormal blood tests or rashes.
At this stage it is impossible to say whether you do or do not have lupus, but it sounds like there is something wrong with you. Most teenagers aren't worried they are really ill, so what ever you do have, I think it needs to be investigated better than it has been so far.
