Has anyone suffered after effects following a severe anaphalatic reaction to pen!

Has anyone suffered after effects following a severe anaphalatic reaction to penicillin but months afterwards?

I had a severe reaction back in March where I became hospitalised, then had to have two weeks off work then returned. But I have been feeling off colour since - especially a little breathless, which I didn't suffer with beforehand. Anyone else experience effects month afterwards and if so what? The medication I had been on was a course of Amoxicillin.

My daughter was rushed to hospital after an anaphalictic reaction and is suffering with blurred vision, and breathlessness six months on. The doctor has advised us that her sight may not recover and is a side effect of oxygen deprivation suffered whilst her teacher and the school nurse argued over whether or not to use the epi pen, and decided to wait on the ambulance. Permanant effects are however not common if medical assistance is provided immediately.
