Hey guys, I'm 19 and got my tonsils out 3 days ago, I'm eating okay and drinking quite easily, have horrid breath, but in my scabs at the back of my throats on both sides is a purple string like form on both sides, and I'm worried because I can't see and pictures of anyone else with it, or and writings about it

 

can anyone tell me if this is normal or if I should ring up the hospital to check? 

Little bit worried
