I had pain in my shoulder for a few months & it hurt to reach up or out. Now extreme pain in bicep with a lump across my upper arm. What could it be?
Bicep painwith lump
There are many causes of shoulder pain: tendonitis, bursitis, sprain or even tear of the rotator cuff/the ligament/muscles which hold hand together. These when inflammed reduce your ability to raise your shoulder/arm.
A lump usually suggest either a torn muscle, a bicep ligament tear, a cyst, ect.
You need a physical exam and an MRI of the shoulder.
