Bump On Elbow Looks Like Pimple. Often elbow lumps are the result of an injury such as a blow to the elbow. It can occur on skewed site as in your son or can occur at multiple other sites too.
When a person has bursitis it is an inflammation of small sacs of fluids that help your joints move smoothly. People can treat most elbow bumps with over-the-counter medication or rest. Bumps on elbows can appear due to a number of different causes ranging from an eczema rash to a large painful cyst.
Its not dangerous but if you want it removed you should see your doctor.
Squamous cell carcinoma looks like a pink or red bump that grows over time. This may look similar to a pimple. I had another one just like it about a month ago and it went away but now its back in the exact same spot. On my right elbow what started out appearing to be a pimple in about February that I picked at now looks like a ring of red bump.
