PLEASE HELP ME I can’t take it anymore!

Okay I have posted about this before but no one answered it so I am trying again but I am having this problem and I am freaking out now. A few months ago I noticed this smallish lump that feels like a little ball deep under my skin (not on the surface like a zit) that was on my vag like above my clit and a little to the left and it was super tender to the touch and sore and then it just kind of deflated and i forgot about it for a few months and now it is back out of no where and it’s very sensitive and sore and keeps annoying me. Depending on what position I am i will feel it more and sometimes it feels mushy and deflated but idk I am going to make an appointment but I am actually terrified and I don’t know who else to ask about this so has anyone experienced this before!? Please help me
