Health Anxiety, please help

So 4 days ago my elbow started to hurt a lot, so after three days of it hurting I went to the doctor and he order some X-rays, the diagnosis was tendonitis,
but this morning my upper right back started to feel warmth and had a little bit of pain, I know there's a good chance that is because of the elbow tendonitis, or because I slept in a bad position last night. The problem is that now I am thinking it might be MS, and then I start to worry, even do deep bottom I know if very unlikely, what do you normally do when this happens???

Give it a few days. See what it is like then. Now during these few days try and not get worked up about it. If you do that it won't go away. Try and find something else to think about. Is very easy for a muscle or the likes to begin hurting in the back. We sleep in a bad position or bend the wrong way. Anything could have caused it. But it does mean MS.

Thanks for you reply, I appreciate it, my back isn’t hurting anymore it only lasted like an hour, I was overreacting/overthinking.
I guess you meant it doesn't mean MS (instead of does),
