New to medication

hi i am new to medication - just over a week since i started on Cobardopa/Levadopa 12.5/50mg. I have had no side effects at all but only very minor improvement so far, my walking seems to have smoothed out a bit and my writing is more legible. My main concern is my right arm, my Bradykinesia has not improved, my shoulder is weak and as i am a painter/decorator by trade i am going to find it very difficult to paint with my right hand. I have not been able to work for the last couple of months but am returning to work this week as i cannot afford to stay off any longer. My question is in other peoples opinions will things improve significantly soon? after 1 month i am due to increase dosage to 25/100mg.
Many thanks
