I have had two foot reconstructions. the last surgery i had a z cut done on my achilles' i am suffering from tendonitus can my tendon rupture easier?

Achilles: Certainly this is a question you should have asked your surgeon. Having said that , if you follow your surgeon's directions to the letter and allow healing to take place you should be fine.

Achilles....: This is certainly possibly in the short term, but depending on how the surgery was performed, the long term results can show the tendon to be just about as strong as it ever was.
