I was just laying in my stomach and i arched my back , kind of like a yoga pose i lifted my head up and i ran my hands down either side of my spine. I felt a medium sized firm/not soft but it wasn't rock hard, lump on my left side. I did have some rib pain directly above the lump back in december 2019 that lasted a few months but eventually it stopped. I suffer from extreme anxiety, so going to the doctors (especially during covid) is a very hard task for me. I need some advice. 
 

Some background on my lifestyle, i lay down a lot, i barely work out, i am mainly sedantry for the last year 2020 due to covid. I did some light workouts for a few weeks this year but i've stopped since the middle of march. Not too sure what it is, i can see the lump if i arch my back but if i stand up i can't see it. It's also not painful if i press on it. 

Thanks
