Cyst on my gum please help

[maxp963]

I am very tight on money because of Covid-19 and don't have dental insurance so I'm trying to avoid going in if possible.
The past few days my tooth was hurting if I bit on it too hard and it was very sensitive to cold liquid. Today I woke up and my tooth no longer hurts but my gums above that tooth is very very swollen and now discolored. There is surprisingly very little pain at all, just discomfort because of how big it is.
I was clenching my teeth a lot the night before my tooth started hurting so maybe its a fracture? but my tooth doesn't hurt anymore so I'm very confused.
I have attached a picture. Do I need to go in to the dentist? Please help.

Sorry, it's only a guessing game based on the image. Based on your symptoms, I suspect the tooth root canal is necrotic (dead) and is a source of infection (swelling). I suspect the tooth needs extraction. Try to go to a community dental clinic for evaluation.
