Terrific that you have good support at both work and home! Well done on the exercising too ..... there will be some reduction of arm movement after surgery - but just follow instructions & don't overdo it too early .... Wise not to attend the studio just yet ..... the 20th will come round quickly enough .... and when you're fully recovered, get back into it.
Absolutely, night time is the worst for tinnitus ..... with everything going on during the day you don't notice so much - but at night time, it is like the volume has been turned up 150%! grrr
All the best for your CT tomorrow @lovemoon xx. That should give you peace of mind (after the bloody wait! ;) )
