Would your insurance cover the test? If you will have to pay out of pocket, then I would wait until a doctor asks for it. But otherwise, it's really up to you. It doesn't sound like it's so bad it's urgent that you get it checked- so it comes down to peace of mind. If it would make you feel better to have the test done, then go for it. But if it would just make you worried and stressed, then I wouldn't bother.
If I remember correctly from your previous posts, you have an LLMD- is that right? I'm just wondering, because you seem to be in a bit of the same scenario I was in for a while. I had to do all my own research on the internet to find Lyme disease, and I got used to having to google stuff myself, since my regular doctor was not very helpful. The problem is- and I don't want to inuslt you, I'm just speaking from personal experience- it's easy to get into a cycle where you start googling every symptom, and worrying about what it might be-because you are used to having to sort everything out yourself. NOTE- once again, I am not trying to insult you, or say you are a hypchondriac. It's kind of the opposite- you were sick, but no one would listen/help.
And because Lyme screws with your body so much, you no longer know what's "normal" and what is not. I found myself thinking and worrying about my health 24/7 for a while, until I realized what I was doing, and made a conscious decision to try to stop.
If you have an LLMD, from what I've heard, they are amazing not just because they treat Lyme, but because one of their basic precepts it to LISTEN to their patients- so they are very good at finding other things that are wrong (although usually I think it's just Lyme). So you can relax, and know that you have someone who is looking after your health properly, so you don't have to do it all yourself.
I really hope this came across how I wanted it to...I just noticed that you really seem to be having a tough time lately.
