i have some very mysterious problems with my left hand during the last 2 1/2 years. It begans with some pain after playing the guitar. Everyone said "maybe you have an overloaded sinew".
Then i rested from guitar for about 1 month. In addition to this i got one of those wrist splints + lots of disinflammatory salves.
I've got MRT / NCV / ultrasonic / lots of X-rays / ...
All of them seemed to be okay except of two things:
1) my ulna is a bit shorter than my radius (ulna minus variance)
2) my carpal tunnel isn't as big as it should (or could) be (according to ultrasonic) but NCV is alright
I've got also physiotherapy and a radiation therapy (worst decision ever..).
Now the interesting point: "Hard work" like gardening, filing, weight training and all that "hand work" stuff works perfectly.
Example: I make an apprenticeship as an industrial mechanic. These kind of work seems very good for my hand. (Means: I get no or less issues from it)
BUT: Fine motor skills are very bad for my hand.
When i take up the guitar and play very easy things for about 5 minutes everyday i get those ******* weird feeling back despite of a longer time of physical rest.
I get sharp, tingling, blazing pain in my carpus / thumb. This feeling is radiating to ellbow and shoulder by time. It's more like a "passive" pain. It cames mostly when the strain is over. But then it remains.
The same thing fits to piano, tastatur, ...
What could it be? Of course, i'm glad that i can do my job but i want to play guitar as i play guitar before march 2009 - without pain.
Nothing seems to make it better...
Yeah and sorry for my weak language skills. This isn't my native language
