Left to my own devices symptoms and conditions

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.
