I miss you though.

Question

Do they mean the same thing?

I still miss you.
I miss you though.

Answer

Well they both indicate that the speaker misses you. However, 'still' and 'though' have different meanings. "I still miss you" = I continue to miss you. "I miss you though" = "But I miss you". So they are not interchangeable.

Answer

Adding to what Claire said, “I still miss you” can also mean “I miss you even so”. For example, this conversation:
1:  “I have been a terrible friend”
2:  “Well, you could have been nicer at times.”
1:  “I guess you don’t want to see me again, right?
2:  “Wrong. Difficult as you may sometimes be, I still miss you. “
