I thought I may have tennis elbow since I do a lot of yardwork & repetitive motions like pruning. Then, I wondered if it could be a boil. It was painfully swollen all around elbow, but I iced, elevated & rested it. Now, most of the swelling is more centralized to my elbow. It came on rather suddenly. A dull, but sensitive pain on Monday, then I woke with it hurting & swolen. Wednesday & Thursday better, but elbow is more red & I still have swelling.
Hello, In my opinion swelling, pain and redness on your elbow are caused by overusing your arm during the yard work.  Considering the description of the location given by you, I think you might have developed elbow bursitis. It's a common problem that follows overusing your arm. I suggest you to: -Keep your elbow in rest.-Continue using ice packs because it decreases inflammation-You can take anti-inflammatory Chat Doctor.  It's also important to try not to overuse your arm, so you can prevent other episodes of bursitis in the future. Hope I have answered your query. Let me know if I can assist you further. Take care
