First time I had that done it ached for a day or two but then sorted the pain and I got the motion back.
Couple of years later it came back and I had it done again – no aching and two injections that time – one from the top and one from the front both into the inter bone area of the joint (I think – I get squeamish and don’t like knowing exactly what’s going on).
That was four years ago and although I get the odd ache and twinge it’s not really a problem – considering I did 25 seasons of rugby, I’ve always walked the hills and spent the last 14 years mountain biking (still rubbish by the way – did you know I came last at SSUK?) I think I’ve got off fairly lightly.
May work, may not but the shoulder is not a painful one provided whoever is doing it knows their stuff
