I ve been experiencing a lot of discomfort below my elbow... limited mobility..even lifting small objects seems difficult.

Is there swelling: in the elbow along with the pain? What do you do daily in a routine that could have caused elbow pain? Often it is associated with repetitive motion from, say, heavy weight lifting such as dumb-bell curls, or hyperextension of the elbow such as when operating heavy machinery that requires a lot of lateral pushing. Visit a healthcare provider with this information in mind. And ice and rest it.
