Hi,looking into your issue,you can do an post surgical doppler or angiogram to study the success of the surgery. some patients do have pain when the circulation is restored called as reperfusion pain.as there is a wound in her toe it may be the cause for the pain. hence the infection should be controlled with antibiotics.the status of the underlying bone should be assessed with an x-ray. regular wound dressing with saline needs to be done. if pain persists and ther is wound in the toe an amputation
could be done.so these are the various options and need to decide according to the situation.safe health.
