How to treat a catheterization site knot?
Patient: the sight where the cath entered for my heart catherization was not sore, but this morning it is very sore. Last Friday, I saw the cardioolgist---he said there was a small knot. At that time what I felt was more of an annoyance. Today it hurts more. I do not know if the knot is bigger, as I did not feel it last Friday. The heart cath was July 10. Doctor: Hello and Welcome to ‘Ask A Doctor’ service.  I have read your question closely, I understand your concern and will be helping you with your health related problem. This can happen, a local scar can be there and inflammation can cause pain and swelling. I would suggest you not to panic just take ibuprofen for pain and inflammation. Ice the area thrice a day this will help with the knot and inflammation. This will get better with time. Local pain killer cream or balm can help too.I hope this answered your question, if you have more queries I am happy to answer you.Regards,Dr. Muhammad Ahmad
