yes you have injured the nerves going into your hand from the repretitive percussive trauma from the hammer's handle and the other tools you mentioned.
It can take over a year for nerve damage to finish healing as much as it will. What you can do to assist your body in healing is to add a b-complex vitamin to your diet regimen. If you see a neurologist this will recommend this to you. Additionally, they may do nerve testing to evaluate the conductivity of signals through your nerves and into the muscles as well as actually monitor the degree to which your sensations are coming back to the fingers.
Your primary care physician can also order these tests - EMG and monofilament tests (they perform monofilament sensation tests on diabetics in their offices to monitor any peripheral nerve damage in diabetics)
Avoiding using those tools is the only way you can stop progression of these symptoms and permit your body to repair.
There are hammers with vibration reducing handles and grips that may help if you need to continue using a hammer, however I couldn't recommend even continuing with that
Did I provide good service?
yes but it is not complete numb because i still feel it when touched
Yes but you have lost some nerve function. The degree of deficit can be evaluated by these tests and over time they can reevaluate you and determine if you're getting function back.
And they will likely recommend you take a b complex vitamin to assist in optimizing your recovery
and this morning the numbness on three fingers on my left hand is almost gone but left with tingling
Full recovery will take up to a year for nerve injury. If you begin using the hammer again you will only serve to halt any healing and injure yourself further.
but my right center finger feels heavy everytime i wake up even this morning,i hope it is still part of numbness,i also find it painful to bend in the morning
It is probably part of the numbness. Do you sleep on your hands? or with them under any part of your body?
Just as with people who have carpal tunnel syndrome, wearing a wrist brace while you sleep may keep you from further exacerbating your injury.
no,also when i do washing with cold water
This is related to your nerve injury. Possibly some arthritis as well to account for the pain in bending the finger when you wake up and the reaction to the cold water, but most of these symptoms are due to your repetitive nerve trauma.
