@dingus I do not remember this whole thread so if what I'm going to say is a repeat please excuse me. I just want to suggest that you not put all your eggs in the Reclast basket. But to leave open at least a small possibility that it could be something else going on and that something else could be important to know about. I'm not doubting your symptoms and the sequence of events certainly points to Reclast but sometimes we can be mislead by the sequence of events.

Example: my wife has had 2 knee surgeries and a torn hamstring that she never fully recovered from, all in her left leg. When she started having more weakness in her left leg we assumed it was related to all the past trauma in that leg. She started seeing orthopedic doctors and sports chiropractors and doing physical therapy and other body work. Nothing helped and she started having more trouble coordinating movement in that leg. Finally the PT said to her "this is not right, your muscles are stronger and you are not improving, you need to see a neurologist". Well, she had Parkinson's. Within a minute of walking into the neurologists office he said "it looks like you have Parkinson's but we'll do tests to confirm that". None of the orthopedic docs or the chiropractors had even thought of this. Nor had we. We were all mislead by the prior traumas to her leg into thinking that the previous physical traumas to her leg were the cause of the current issues.
Just in case anyone thinks I'm suggesting you have Parkinson's or some other terrible disease - I'm not suggesting that. Only offering this as an example of how we all can be mislead including the doctors. Best of luck to you in finding a solution
