Could it be Gout???

Hello to the group.....I have just joined thinking I had gout. My
big toe became inflamed, swollen , hot and painful two weeks ago
yesterday. Nothing has really seemed to help it. Walking at times
has been impossible. The end of July I had ankle surgery on the
same foot which included a tendon transfer and a calcaneal
osteotomy. I initially thought there must be some problem as a
result of the surgery. I had only started full weight bearing two
weeks before the big toe problem, so to become immobile again has
been very difficult. Then after such a long period of time and the
swelling never going down, I thought I must of broke it, although
there was no acute trauma to my toe. Finally, after searching for
answers on the internet, gout sounded like it fit my symptoms.
Yesterday, I had the uremic blood test and x-rays. My level was
normal and the x-rays showed nothing, so my primary physician said I
need to talk with the orthopedic surgeon when I see him tomorrow as
the pain may be the result of a problem from the surgery and if its
not, she'll explore the problem more. I have read several of the
posts, but wanted to ask if one could have gout without the tests
revealing that.
Thanks for any information.
