What I was originally told was tendonitis, appears not to be that.
I have a lump on my inner elbow that has grown quite a bit, I showed it to my doctor (I went about something else). She muttered something about an ultrasound and it being a lymph lode but got distracted with something else. She forgot to arrange an ultrasound and I left, also distracted with something else! 
Any thoughts? I'd quite like it removed if possible, it's irritating when I bend my elbow.
