Advice

So... im probably jumping the gun here a little bit. 

For the past month I have been suffering with horrendous night sweats, to the point t I need to get changed in the night, sometimes more than once. I thought nothing of it, however now I have noticed a pea sized lump on the back of my neck neck to my spine on the left side. Obviously I did a bit of Googleing work and well I'm rather shocked of the results my searches findings. I have so been feeling pretty fatigued of the past few weeks, which I put down to the change in weather. I'm awaiting a doctors appointment, due to all this covid stuff my doctors are being pretty *** with appointments. 

I know im probably just getting myself worked up. Thanks in advance.
