I (Jenny) have been having some problems with my right shoulder.
A couple of years ago I had a frozen left shoulder and so I thought that the same thing was happening with the right.
It turned out to be tendinosis with secondary capsulitis (frozen shoulder).
I have been helped a lot by Khun Nat, a lady physio therapist at the local McKean hospital.
When Mum was hear over Christmas, I took her along as well and so we spent time together "on the couch" for two sessions each week. Khun Aa could speak some English and was able to help Mum quite a bit.
I can thoroughly recommend the PT department at McKean. It is inexpensive and they give very good care.
