Missing almost half of my columella from rhinoplasty and alot of scar tissue in right side of nose that is painful

Yes, but you should get evaluated by an expert rhinoplasty surgeon who can better determine your potential options.

I think that your columella scar and retraction are very correctable. It will likely take some cartilage grafting. 

    There may be room for improvement, but photos or an exam would be necessary to make that determination.Kenneth Hughes, MDLos Angeles, CA

Rebuilding a columella can be one of the most difficult challenges in rhinoplasty/nasal reconstruction. So seeing some pictures of the actual problem is needed before any meaningful comments could be made.

Thanks for sharing your story.  It does sound like you have quite a bit of scar tissue.  You will need an in person consultation with a board certified plastic surgeon that is comfortable with revision rhinoplasty.Best of luck to you

Unfortunately without photos and an examination it is impossible to make an intelligent response.  That said go on consults where someone can examine you and get opinionsDr Corbin
