Unable to Edit my recent post (is it only Me)

Hi Guys,

I am unable to edit my recent post coz the link to edit post is missing from the bottom links of the post. I tried it so many times but couldn't find anything to edit my post.

Am I missing something???

Edit : All right, the edit link stays there for a while (at least for a couple of seconds Or mins after starting the thread Or post) as Im seeing with this post but what If I want to edit my post after an Hour Or couple of hours?

I cannot edit/delet post, too!
Why?
