How long will this last?
Honestly: one to three years from start to finish, across three phases — painful, stiff, then gradually thawing. That is a difficult thing to hear, and knowing it at the outset is considerably better than discovering it slowly while assuming something has gone wrong. Most people regain good function.
Should I be stretching it?
It depends entirely on which phase you are in, and getting this wrong is common. In the early painful phase, aggressive stretching increases inflammation and makes things worse — gentle movement and pain control are what is needed. Once the pain has eased and stiffness dominates, stretching is exactly right and should be done consistently.
Is a steroid injection worth it?
Often, yes — and timing matters. An injection has its best evidence early, in the painful freezing phase, where it reduces pain meaningfully and may shorten the overall course. It is less useful once stiffness rather than pain is the main problem. If you have diabetes, expect your glucose to rise for several days afterwards.
How do I know it is frozen shoulder and not a torn tendon?
External rotation. Tuck your elbow into your side and turn your hand outwards. In frozen shoulder that movement is genuinely blocked — and it stays blocked even when someone else tries to move your arm further. With a rotator cuff problem it hurts, but the movement is available.
Why has this happened to me?
Frequently there is no trigger at all, which people find genuinely frustrating. It is not caused by overuse, sleeping awkwardly or anything you did. It is more common in the 40 to 60 age group, in women, after a period of immobilisation, and — substantially — in people with diabetes or thyroid disease.
Why do I need a diabetes test for a shoulder problem?
Because the link is strong: diabetes raises the risk several-fold, and frozen shoulder is sometimes the first sign of diabetes nobody knew about. It also matters practically — people with diabetes tend to have a longer, more stubborn course, which is useful to know in advance rather than experiencing as an unexplained treatment failure.
What helps with the night pain?
Three things, all worth doing together: sleep propped slightly upright, support the arm on a pillow across your body so it is not hanging, and put a pillow behind your back to stop you rolling onto it. Time your painkillers for bedtime rather than earlier in the evening. Night pain is the hardest part of the freezing phase, and it does pass.
Will I get it in the other shoulder?
A meaningful minority of people do, though usually not at the same time. The useful part of knowing that is recognising the pattern early next time — particularly the loss of external rotation — since being seen during the painful phase is when treatment has most to offer.
