Left eye won't move inwards after strabismus surgery

I had strabismus surgery performed on my left eye about 2 weeks ago. The inner muscle (closest to the nose) was, according to my surgeon, very tight, and it pulled the eye inwards. So he moved the muscle further back on the eye. The results are really nice. Except that there's one problem. I can't move my left eye towards my nose anymore. Well, not completely at least. I can move it a little bit inwards, but after a bit, it's just stuck and won't move further. When I look all the way to the right, I see double, because my right eye is able to move into that direction, and because my left eye can't, I see 2 different images.

I tried really hard to kinda force my eye into that direction, but it just hurts and it simply won't move. I think there's something wrong with the muscle now. Will this ever improve? Is this muscle "weakened" like this forever? Can a weakened eye muscle be trained somehow?

Thanks in advance for any helpful replies.
