Answer
Nabin,
You should have your hand x-rayed, this will tell if there is a fracture or maybe a misalignment in one of the joint spaces. You can have it x-rayed by a Doctor of Chiropractic or a Medical Doctor and either doctor can tell if it is broken, but only the Chiropractor can see if it is misalgined and correct the misalignment.  If this is very recent, then it may just be pain and swelling from the injury and may need more time to heal.  I would suggest that you have it looked at further and explain to the doctor what you are telling me.
Let me know if there is anythign else that I could do for you, good luck.
