Neurology appointment?

Hi I’m Tasha and I’m 19, recently I was admitted straight from the doctors to the hospital because I had a problem with my heartbeat. I was admitted for 4 days and whilst there I experienced numbness in my legs, the doctors checked for obvious signs of the cause but when I describe my other symptoms of my muscle weakness and pains in the last few months, they said they would book me in for a neurologist appointment in a few weeks. I had bloods taken for a special test but not the results back yet. I got a letter saying my appointment was booked for the 1st April but I got a call from the hospital saying they needed to see me on Tuesday instead! Should I be worried they’ve brought it forward?!
