I had the same sort of problem although it was with my ring and pinky. Not as bad as you seem to have it, but it was a problem. I think it's just a natural problem with your hands mechanics. Something you can try which helped me with my pinky and ring is to try playing finger patterns just using those fingers. Try this exercise.

At first this exercise may seem fustrating since your concentrating on using only the fingers that are giving you problems. But if you sit down each day for a minute and run through it before trying the solo your working on. It will definitely help or at least I hope it helps you. Don't worry about speed just play it at a tempo that you remain in control. The best way to overcome something that is giving you problem is to isolate it, and kick it's a$$!!

Don't beat yourself up over it, especially the first couple of times you try this exercise. Your fingers are going to act the same as before, but if you stay relaxed; your fingers will eventually calm down and they'll gradually work the way you want them to.
Good luck! :)
