Im a 39 year old male. I had a triple bypass last year in May. After the surgey, my chief complaint is knee pain. In both knees. Mostly in the left knee though. I can some what understand if it was just one knee, but this is affecting both. It seems to be worse when it is about to rain. My heart doctor is dumbfounded and I have seen a pain specialist. The pain specialist thinks it is phantom pains. I have had several xrays, and nothing showing. I am taking several medications, but we have tried dropping and changing to see if they were causing it. Do you have any suggestions?
