Heart catherization symptoms and conditions

I suffered cardiac arrest in 2006 with the only change in my 51 y/o basically healthy lifestyle was i started taking 500 mg/day of levaquin four days prior to my collapse in front of my students in the classroom. I am a 4th grade teacher - I had suffered cardiac arrest at least three times before I was treated with Arctic Sun therapy to help recover. The heart catheterization afterwards showed no blockage in my heart. There was a good chance, in my opinion, that levaquin could have caused my cardiac arrest. Although not conclusive because I had a tooth infection which was the reason I was prescribed the levaquin and i was taking an said for the discomfort, the back of my mind always comes back to levaquin because i suffered the joint weakness i read in articles of other users of the medication. I also was reminded after the accident that a young person we knew of had died unexpectedly in her sleep a and she was taking levaquin. It makes you think it may have been the levaquin, but no actual proof could be determined by my doctors. However, I will never take this medication again, knowing there are so many other antibiotics on the market to help me.

Took Levaquin for 5 days as a prophylactic measure to prevent infection from a prostate biopsy. Experienced severe Achilles tendon pain and itching and swelling in both feet after the 1st 2 days but did not originally attribute it to the Levaquin. The pain has finally subsided after 12 weeks but some swelling remains. Could barely walk in the beginning and still have some balance problems.
I take no other medications and do not jog or exercise strenuously. I had a heart catherization 1 week ago and all is OK (no blockages). I have been to 4 doctors and only one would say that it might have been the Levaquin. Meanwhile I have been left to my own devices. Found some exercises on the internet to strengthen my Achilles tendons which have helped and found that lotion and massage have helped my feet.

I was injected with Renografin intermuscularly instead of Xyocaine during a Heart Catherization procedure. Have experienced pain in Groin area ever since.
