[|Human|] I had a heart catheterization four days ago. Yesterday I must have strained too much and now I have redness and firmness around the entry point but it is not affecting the entry point which appears fine. I want to wait to see my PCP tomorrow as soon as possible. Is that a reasonable decision? It hurts but the pain is where the redness and swelling are, not at the catheter entry point.
[|AI|]  Helloi have gone through your query. The thing you are having is a hematoma- a blood collection between the tissues under the skin. It happened because of straining, the artery which was cannulated had a small leak when you strained. You must watch out for increase in size of the swelling. Please contact your doctor. Allow rest to the limb affected including weight-bearing. Also if possible keep a cold compress. It may be red now. And the color may vary from red to blue to green to yellow before disappearing. It will take around 15-20 days to disappear. However increase in the swelling should be checked for. You may also be advice to undergo a sonography of local area to see the extent of the hematoma if its quite large or your doctor thinks so. Thank you.
