Hi!
If you go strictly by book then normal blood pressure is 120/80 mm Hg. This can however in practical life vary. For some 110/80, 110/70 or 100/70 or80 is normal. For others 130/80 is normal.
So as long as you are not feeling dizzy, overtly tired, fatigued or sweating profusely, yes, 107/58 can be considered normal. However, if you have these symptoms, please show a doctor. Take care!
