I  have pain in my left upper arm, in the bicep area, but more to the outside of the arm. There seems to be a lump between the deltoid and elbow, about half way down my arm. I have what feels like tennis elbow as well, but theres numbness in my last 3 fingers on that side and sometimes the pain is pretty severe, especially after working a while. I have had rotator cuff surgery along with a reattachment of the bicep tendon about 6 years ago on that side.
Hello dearWelcome to Chat Doctor.come have evaluated your query thoroughly.* This is most likely to be cystic swelling with impingement of neuronal sheath due to underlying pressure.* High resolution ultrasound is recommended for the diagnosis. Hope this clears your query. Regards dear.
