Mr. Dime
Sorry, I hit the wrong button. To continue.

An example is the way that people carry about with them bottles of water. When asked why, most will say only that "it is good for you". That is all they know, due to the advertising.
In 1932 a medical report was made that we need to intake two litres of fluid per day. Most of this is taken in food, which is 70% water.
In the 1990's advertisers of bottled water quoted this report and the two litres of water, but ignored the second sentence. Hence the advertising was mischievous in that it did not paint a full picture.

As I said in an earlier post, some good advice has been given to you by Bonnie Shaljean and Richard Bridge which, if followed, will certainly help your recovery. I made some earlier comments which, again, if followed will help.

I am pleased to see that you have an appointment with the University hospital. When you attend for your appointment take your guitar! Show the medics how you stand/sit to play the instrument. Emphasise the hand/wrist position. If the particular doctor cannot understand what is causing the problem then ask for a referral to another practitioner.

YOU are the patient - the customer, if you like. The attitude of "Doctor knows best" belongs to the last century. Stamp your foot (metaphorically, of course) and insist on the type of treatment you think you need.

Please keep us informed

Colyn.
