Hi Tina,I noticed this after my 2nd sct. Sometimes I felt as if I was going to fall over although I never did. I think it was the aftermath of all the medication I had taken and it did settle down after around 6,weeks. I would bypass the GP and go straight to the Hospital and see your Consultant. Unless you have a really good GP and I know some are lucky in that respect Hospital is the best place to go to get urgent attention. I found when I was sitting down I was ok but when standing I would get a very strange feeling in my head,a sense of unbalance which would come and go.
Good luck Tina and I hope you get it all sorted out for yourself.
Keith.
