Hi @Saladcreamsandwich I broke my elbow almost 10 years ago, & had an op to pin and plate the joint. I damaged my radial nerve (it was pierced by the fractured bone) & had no wrist or finger extension for about 7 months. The good news is all healed well & I have full function of my arm, hand & fingers. It was very painful though, & yes absolutely miserable trying to sleep & just be comfortable for a while.
Two weeks is not a long time in terms of recovery & I would suggest too early to start trying to reduce pain meds. I would advise taking the pain meds at regular intervals (safe intervals as specified by your Dr or the patient information leaflet that came with the meds) so that you are topping up pain relief before each dose wears off.
I slept on the sofa for the first couple of weeks because I found it more comfortable. I couldn’t turn over in bed, but on the sofa I could support my broken arm more easily & use the sofa back to lever my self up if that makes sense.
Physio was great for me , it really helped get movement & strength back in my arm. You will probably need to wait a few weeks before you can start physio. I doubt you could do I exercises with a cast or dressings, but once those are gone it REALLY helps. I ended up making a private appointment to see a physio as there was a long wait for a NHS appointment & I didn’t want to wait. I’m really glad I did, I think the physio was really essential for getting a good range of movement back.
I hope that helps & wish you all the best for your recovery. Hang on in there, I’m sure you will be feeling better soon.
