Lump on shoulder

Hi I’ve got a lump in my shoulder I’m getting pstabbing pains from my shoulder down my right arm and my neck been like this for 4 days now it’s getting worse 

  • Impingement imo ask to see a upper limb consultant.

         Gave me a decompression operation. Never worked out, because it was left to long. Excalated into a slap repair (4 bolts and excruciating 10 week wait followed by month in a sling and then a long road ahead of me with slow phyiso. Advice is push them for MRI and ultrasound? Don't leave it too late. Good luck
