Thank you for your query at DoctorSpring.com
I have read your question with diligence .
Will you please answer some question -
-Is their any swelling at elbow?
-Any history of diabetes?
Patient replied :
Yes, some swelling. No history of diabetes. I am an IT consultant I spend most of my time in front of a computer. I am left handed and it's my left elbow.
Yes, constant pressure can cause a lot of inflammation around the joint leading to pain in the elbow.
Tennis elbow is a possibility, I will request you to get an x-ray and share it with me.
Meanwhile you can take a painkiller like Advil for relief.
