Advice please

Hi all,

Lately I’ve had some things happen to me and I’m no sure if they related.

I’ve been feeling quite faint lately, no specific time in the day. I just feel like I’m going to pass out in moments like this and I begin shaking

Secondly - Sometimes my hands start to burn and itch. Then they begin to swell and go blotchy. It doesn’t happen to both my hands at the same time but it’s happened to both on separate occasions.

Just want to know if this is something of concern before I see the doctor. Could it be a sign of something more serious, if so what?

Thanks
