Question - Elbow Injury (pain with weight lifting)

by Liberty
(Texas)

I been lifting light weights everything was going well and I was progressing. The following day, my elbow was quite painful. It seems to get worse when I lift my arm or put it behind my neck. I have treated with ice and heat intervals. Took Tylenol, and today I took a anti-inflammatory medication. I don't know what to do or why my elbow became painful. My elbow is swollen and the inside of my elbow is painful at times when I tried to bend my elbow. my elbow is limited in range now.

Please HELP!
