I thought this year my newish pear tree was going to be ok.  Last year it suffered badly with red blisters on the leaves and the leaves curling up.
I cut off everything and pruned it really hard back in the autumn and again in the spring.  However, today I have noticed that they are back, though the little tree is covered in blossom!!!
Any suggestions?  Is there something systemic I could spray on whatever it is?
Many thanks

No my pear hasnt got red blisters but it has got what looks like leaf curl 
Its like yours covered in flowers but the leaves look terrible, same last year, almost looks like the curl peach trees get. I asked at the GC last year and she had no idea and then she joked maybe the tree wants to be a peach tree instead

I used to get this regularly at my last house. It's called peach leaf curl but will affect other fruit trees. It's a fungus born on wind and rain and once you get it, its super difficult to get rid of it. I kept pulling off infected leaves and feeding the tree well with liquid fish emulsion (my preference for this) and lots of secondary leaves soon appeared infection free - for that season.

Here's a lot more info on it:
