Yes mine was an ingrown toenail too, and 11.3 is too high, it could be due to stress and what you have been eating but could also be the infection, I hope you get seen today, this is making me really nervous , I am telling you I went to bed with just an infected toe, I put on some cicatrin powder, I woke up at gone 4am, I had a high temperature and the entire foot way past up my ankle was bright red and throbbing, we drove to A&E and I was admitted to hospital straight away and put on antibiotic drips and what not else.
When are you doing exams, poor you with course work, my bg used to go haywire whenever I was stressed with studying, getting assignments in on time and taking exams, its hard to get it all under one hat sometimes isnt it.
I hope you get sorted quick, please come back and let us know.
