Hello my name is Hannah and I am 22 years
Hello, I'm Dr. Branch, thanks for using Ask a Doctor. While it is difficult to say for sure without an examination, the symptoms you describe and the most common cause of elbow pain suggest lateral epicondylitis (tennis elbow). This was likely aggravated by lifting weights. The treatment for this is usually avoiding activities that aggravate it, using a brace (you can search for tennis elbow brace and find many good options). Beyond this physical therapy can be beneficial. Taking NSAID medication like Ibuprofen can help, and if the pain persists, steroid injections can also help as well.
Without treatment, symptoms usually persist for 6 months to 2 years, but hopefully with some of these treatments it can heal sooner than that. I would suggest seeing a doctor if you can, and in the meantime trying the brace and Ibuprofen to see if they help, as well as avoiding activities that make the pain worse.
I hope that helps, please let me know if you have any questions about that and I would be glad to discuss it further with you.

Yes, you don't have to play tennis (or golf) to get lateral epicondylitis, and the pain can come and go depending on whether it gets aggravated by certain activities or not. An examination by a doctor should confirm whether this is the cause of your elbow pain.
Arthritis would not be very likely at all, it is rare to have arthritis in the elbow, and almost unheard of in someone your age. I would suggest you check with another doctor for this.
Hopefully, that helps. If you have any other questions just let me know.
Thank you for your question.
