[|Human|] My sister had a cardiac cath last week.  On the third day, she got excruciating pain in her lower leg along with some numbness. Since then, the pain has continued to get worse. She went to an ER and all tests came back normal.  She is in agony and nobody has any answers. Can you help?
[|AI|]  Hi, Thanks for writing to Chat Doctor, I am Chat Doctor. Catherization is invasive procedure it can have complication like nephropathy, enolization, bleeding etc.as the numbness n pain which is after cauterization is high likely due enolization . If u were my patient I would like to run some test to make sure is it embolism causing pain or DVT (disease causing pain redness n swelling) I would like to have atrial n venous Doppler USG of leg n some blood test, so I can r/u what it is n will treat it accordingly hope this answered your question, if you have more feel free to ask. Regards.
