My girlfriends grandmother who is 77 has been on Lortab for 3 years now because of medical conditions.  She recently had back surgery to repair a disc in her back and had to get 4 vertibre(spelling?) fused.  They did not know she was on Lortab for this long and took her off of them cold turkey.  She was vomiting, spasming, etc.  Now she seems as though she is not all there.  Initially they thought she was putting on a act to get more lortabs because of the trauma she was going through, but now the problem seems to be more serious than that.  My question is that I know one of the side affects of Lortab withdrawal is a increase in blood pressure.  Is it possible that she could have had a minor stroke being that she is relatively old and is overweight?  The doctors don't seem to know what they are doing and they seem to suggest that there is no way this could have happened even though they have not run any test.  Also, she is in a nursing home so that might be why the doctors are not doing what I think they should be.  They just say maybe she has dementia.  I am just curious to whether this could be a real possiblility with the withdrawals or am I just over-reacting?
