Avelox and uti

My Mom (87) who was in great health given her age, was given Avelox for a urinary tract infection. She has developed severe side effects that include shortness of breath,chest pressure, (not chest pain)swelling of her esophagus & eye lids, confusion/agitation, dry mouth,complaints of twitching in her mouth.
The worse case of all the symptoms has been the swelling of the esophagus and eyelids. Her eyes are swollen shut and she labors to swallow & talk. Eating is a monumental task.
She is currently hospitalized and the medical team seems to be having a hard time accepting this as an allergic reaction to the Avelox. They have run series of tests to look for other things such as pnuenomina, heart issues and stroke issues. So far the tests have revealed nothing out of the ordinary. One would think that they would start treatment with steroids or another anti-allergic treatment but they seemed convinced that the Avelox is a non issue because she only took 2 doses @ 400 mg each starting Saturday & Sunday (11/29-30). This ordeal started Sunday early evening.
If anyone else has experienced specifically swelling of the throat & eyes please post!

I was prescribed avelox for mastitis and a UTI. I was fine until after the 3rd dose, I had MAJOR anxiety attacks that would start from my head down through my legs, like a tingling sensation. I felt as if I was going to fall over or faint. I then had tremors or the shakes. Doc said to continue the med after telling him how I was feeling. I then couldn't take the symptoms and went to the ER and they said the same thing, continue taking it. Now my gut feeling was to not take it, but I had a bacterial infection and didn't want that to get out of control, so I took the 4th dose. The next morning, it was the same thing all over again, tingling/dizziness from my head that would run through my whole body, and the shakes again. I went back to the doc and they told me it was safe to stop taking it. It has been 3 days since I stopped taking it and I still feel terrible. Very tired, my head just does not feel right. I hope with each day that it gets better. What a nasty drug this is and For anyone that reads this, please take this warning seriously, you do not want to feel like this. Oh, one more side effect, I had the tight chest also.
