Sigh. Okay, I'll bite.
Anything less than 100F really isn't a clinically important fever. If you have a slightly elevated basal temperature, that's not a fever - human beings vary and not everyone's resting temperature is the classic 98.6. Think of heart rate - normal range is anything from 50-100, depending on all kinds of different factors. Variations from the person's normal value are more important than absolute values - if an athletic young person with a usual HR of 50 shows up in the ED going around 90, that's worrying, but that same heart rate of 90 might be completely normal for someone older, less fit, more overweight, on certain medications etc.
Same applies for your temperature. Low grade temps of 99-100 are only really important if that's a change from your baseline. I really shouldn't have to explain that having a low fever of 101 during an infectious illness is extremely normal and not a cause for concern.
It sounds as though the initial time in Nov/Dec when you had fevers, sweats and the positive ANA, you probably had the flu or something similar, which can last for weeks and leave you feeling pretty rubbish for even longer.
Nothing you've written is a description of someone that is actually having ongoing idiopathic fevers in a way that is concerning. The pattern you describe sounds completely normal, and doesn't raise any flags for having some undiagnosed autoimmune or chronic infectious disorder. It sounds diagnostic for being a human.
Again. Second opinion. Specific health anxiety/factitious illness therapy. Stop the obsessive behaviour (constant temperature checking, posting about symptoms online, asking for reassurance, researching lupus/autoimmune disease survival rates, engaging with forums like this). MOVE ON and live your life. I'm sorry that you're suffering but if you refuse to make any changes to your behaviour then this is not going to change and things will only stay the same or even worsen further.
I fully expect you to take no notice of all of this and continue with your fixed beliefs but my autistic compulsion to correct bad science wouldn't let this lie. Go ahead and gimme dem puzzle pieces, I know what I'm about.
