Bumps below wrist

For the past 6 months i have had painful bumps that lie right on my tendons below the wrist on both of my forearms. They have not changed in size over the past few months, and they tend to swell up if i use my hands too much/lift up heavy objects. The only trauma that ive had in the past year is golfers elbow on both of my elbows from working out.
8 days ago i got cortisone injected into where the bumps are located, but the size and pain of them has not gone down whatsoever. If someone could, please offer some insight into this problem and what can be done to relieve the pain.
Ive attached a picture of my right arm highlighting the location of the bumps. ( there are specifically two eraser head sized bumps on each arm).

Hi there!

Well, without a physical examination and probably a few tests, it would be difficult to point out the cause of the swelling in your case. Possible causes include osseous outgrowths, abscess, cysts, granulomas, loose bodies etc. It would be best to get this evaluated by an orthopedician at your earliest convenience for an accurate diagnosis and appropriate treatment. Meanwhile you may try some OTC NSAIDS for pain relief.
Hope this helps.

Take care!
