Yep, be careful of that! Give your hands a lot of rest. I have the same problem and sometimes I can’t even sleep because of the pain in my fingers and wrist, trepidation, pain…
That’s carpal tunnel coming and if you keep overworking your hands it can get you to a really unpleasant operation… And be careful of mobile phone, holding it all day to browse, write or play games also worsens the problem a lot! When getting worse, you can stop feeling in your fingers altogetherr and in this stage it’s irreversible, so it’s really dangerous. Rest your hands a lot!
