Turns out my shoulder/arm pain was due to calcific tendonitis – a build up of calcium in the tendon. Apparently the painful phase is when the body starts to reabsorb the calcium and it can last months.
What they did was give me a local anaesthetic then using ultrasound, aspirate the calcium, which has a consistency of toothpaste at this stage, then inject a corticosteroid.
Pain relief was virtually instantaneous and while I’ll need physio, I already have a lot more movement of the arm. Have been able to stop oramorph.
So, nothing to do with the myeloma, I’m still in remission it seems.
And I ent ded.
