You are either wanting to get back to the forum page or edit your post.

If you want to get back to the forum, wait for it to load, dont click back, then click Forum name, then go, down the bottom right corner of the page.

If you want to edit the post, wait for the page to load again, dont click back, and then click edit, which is at the bottom left corner of the post you just posted.
