It may be due to the position change (3rd being a bit more 'scrunched up') but I've been doing studies in 3rd position for the last month and haven't noticed any soreness. As you've said, worth checking to make sure it's not incorrect hold/posture. I find 4th finger, particularly on G string, really uncomfortable!

Thank you LooneyTunes and Lottie,
when I first started playing violin I didn't get any soreness ANYWHERE! But I do know that some people get sore neck/wrist/arm etc as they are not used to be in the violin playing 'posture' and so they tense up. Maybe it was 'natural' to me and I didn't tense up and that is why I was ok, but maybe I am now tensing up in third position? At the moment it's not getting any worse so I might be ok. Will keep you posted

I think tension can start when you begin with third position. When you are a complete beginner everything is hard and perhaps you have low expectations and can be relaxed about intonation and finger movements. As you get better you get very confident in 1st position as the hand is in the same place and the finger spaces are all familiar so the notes arrive in tune relatively easily. Once you start shifting all your points of reference are lost - thumb position, fingerspacing etc. This can lead to a feeling of insecurity and you can start to grip the violin. It sometimes feels necessary to press fingers harder in higher positions to get a good tone which can also lead to tension. Also 4th finger gets used more as there are less open strings. Repeated movement of the fingers when the hand is tense and gripping is a big source of wrist pain.
So try and keep the hand very relaxed and don't grip. Obviosly ask your teacher to check your posture but for self help check:-
that your left wrist is straight not tipping your hand backwards,
that you are bringing the left elbow properly under the violin so you can reach with 3rd and 4th finger without stretching the wrist - elbow comes further under in 3rd pos than in 1st I think,
look at how your fingers are pressing down in the fingerboard (esp the 3rd and 4th) - the last section from the last joint to the tip should be near vertical (requires the elbow to come well under especially on the lower strings) this enables you to get the string well stopped down with hand and arm weight alone without squeezing the neck hard.
A little test of finger position. With fingers on the string reach over with the bow and tap the fingers with the wood of the bow. You should get a nice clear tapping noise.
Another thing of interest to some perhaps. This newsletter has an article on how setup can effect left hand comfort. It is aimed at cellists but some of the info is applicable to upper strings. I am not suggesting at all that you start changing strings or setup jojo as I doubt that is the problem, but I thought it was quite interesting
