I Had a Tummy Tuck 6 Months Ago and my Skin Has Not Attached to the Muscle is This Normal?

I'm not quite sure how you would know that but there should not be a cavity/space between the muscle and skin at six months.  I would seek the counsel of your PS has how he/she would like to proceed.

I'm not really sure what you're describing but having detached skin I'm not sure is impossible. Any rate get checked by your plastic surgeon and have them explain to you what the problem is.

Your question is rather vague and skin usually attaches to the underlying muscle if you did not have problems with fluid collections plague you during your recovery.  It is not unusual to have some redundant skin at the upper abdomen.  Is this what you mean?

I can only assume that you have some loose skin above the umbilicus and above the scar.  If it is loose skin above the scar then this can be revised.  Above the umbilicus is  a more difficult correction because it requires a re-elevation of the  whole abdominal skin flap.  

You will have to explain the meaning of this. Perhaps a photo would help if this is visible at rest. All the best.
