Lump on back of neck

Male 22. I have gotten lumps on back of neck before but usually they aren't this big. What is it? Should I put lotion on it or could that just end up irritating it more than it already is, also it doesn't hurt. And to add to that 2 months ago I had a bigger size lump on my throat area. The doctors ruled it was cellulitis, not sure if this is the same thing. I made appointment to be seen and the closest I could get was March 10. Is this something worth escalating to urgent care? Sorry for the info dump,any help will be appreciated.
