Andrew Sa, I understand what you mean. When I first started learning scales, I didn't know what the hell to do with them. The best thing to do is to learn other peoples solos. You can steel bits and pieces of them and put them together, eventually adding some of your own notes. All it took for me was to learn a simple minor pentatonic SRV lick. Then suddenly I knew what to do with that scale. Another thing you can try to learn what to do is hum some notes that sound good over a chord progression and then translate those to notes to guitar. Often solos are based on the melody sung over the guitar. Also, note that whether borrowing from someone else or what you have sung, make note of which scale pattern you are using to solo. This will help you when improvising.
