[|Human|] For the past couple months or so, Ive noticed this lump on my forearm, just below my elbow. It feels hard but when I touch it but it doesnt seem to be attached to the bone. On top of the lump, on the skin, there are always little lump bumps all over. Im not sure what it could be.
[|AI|]  Welcome to Chat Doctor .1. The history given by you suggest me- the most possible cause could be ganglion cystic structure arising from tendon, bursae, nerve sheet. 2. They are generally pained less lumps adjacent to joint space.3. Your further step should be got an ultrasound lesion / lump done.4. Ultrasound will evaluate the source of the lesion, its content and where it is extending. 5. But best investigation of choice is MRI joint - good tool for evaluation of nerve, tendon, bursae, nerve. And content of the lump. Good luck. Hope it helps you. Wish you a good health. Anything to ask ? Do not hesitate. Thank you.
