Dizzy spells are a classic anxiety symptom...as is tingling in the extremities. I am not trying to poke fun but if the number of people on this site who think they might have MS actually had MS it would be an epidemic! One reason so many people feel this way is because anxiety mimics so many of the symptoms...only difference is that anxiety is very common and MS is very rare. The other reason is too much googling (stop it now!) and misleading/panic inducing sites like web md (which once diagnosed my hubby with a cocaine addiction because he was grumpy and wanted a beer. btw my hubby has never even seen cocaine much less used it.) Trust your doc, try to relax, and hang in there!
