Regressing?

I don't like it when things appear to backslide.

Especially when it's medically related.
How I've had some issues with the lymphnodes in my arm. Where they've been swollen for months...but now are finally starting to heal and go away.

Only for a couple of them suddenly to appear to be swelling again.

But I don't know if it's something to worry about.
Or if, since I was doing a lot of things with that arm, that involved brushing against the nodes, that I just irritated them a bit, it's actually nothing to worry about, the apparent swelling is nothing....

Who knows.
How long before I have to actually worry that the progress has reversed and is now regressing?

So...Headache.
