Beethoven Sonata - help!

[qwerty quaver]

Hi!!!

I am currently playing the first movement of Beethoven's Sonata no.3 op.2 no.3. (the one where there are thirds* in the first two bars at the right hand, see the attachment).

from bar no.97 to 108, I experience a lot of muscle tension and cannot get through all the semiquavers*.

furthermore, I cannot practice this movement too long, because I get shoulder pain due to the partial recovery of a shoulder dislocation.

How can I practice without pain and get those bars right?

I understand that one has to know the piece to comment but I would really be thankful for any advice.

* I hope I have correctly used these terms to describe the specific places I am referring to since I study under the French system and am not familiar with them...

I personally don't know the piece, but maybe it has to do with your posture at the piano?
