Thanks for sending the pictures.
The pictures are not that clear enough for me to comment. What I can definitely make out is definite
redness with swelling in the elbow region, in which case
brufen might help.
However,If you have
fever, can't bend your elbow, or if the area becomes swollen, red or warm ,if there is pain or tenderness, if there are red streaks on the arm or forearm.... all are signs of inflammation and infection, that you definitely need to visit the doctor.
If it is infected, just brufen might not help. You might need to get the fluid drained and be started on a course of antibiotics.
Note: For further queries, consult a joint and bone specialist, an Orthopaedic surgeon.
