Suggest Treatment For Swollen Gland On My Upper Neck

Hi,
I am a 14 year old female.
I have a swollen gland on my upper neck on the right side, next to my cheek bone. It is only a small swelling and it is aching. I had a small grass tick above my ear 4 days ago and it began to swell a day after. Also i have a cat who is allowed outdoors and she scratched my eyelid on the same day as discovering the tick. I am not sure if there is a connection between the two issues or not.

This gland has never swollen before when i have had a tick in the same place. It actually has never swollen in my life. I am concerned if their might be a link.

The swelling is very small, 1cm by 1cm circle approx. It is causing my neck to ache.

What could be the cause? The tick, the scratch or something else? Also should i see a doctor, or call someone? Should i be worried?

Thank you very much!
