Why am I having a big hard lump in my groin 2 weeks after radiofrequency ablation?

Two weeks after ablation I started to develop a huge lump on my groin. It is getting harder and it seems like it is moving upwards and getting more painful everyday.

This may be at the beginning of the ablation area, near the saphenofemoral junction in the groin. You should return to your surgeon for a follow-up ultrasound to ensure this is just a normal part of the healing process. Normally by two weeks you should be well into the healing process and pain (if any) should be greatly decreased. Occasionally, after about 10-14 days, there may be a slight increase in discomfort when the deeper swelling is resolving and the nerve endings are "waking up." However, an ultrasound should be done with your symptoms.

The description is somewhat concerning. "Started in the groin and moving higher ..." Above the groin, you are likely getting into the pelvic area and if you feel a lump there, that is concerning. Contact the doctor that did the procedure immediately and get a venous doppler ultrasound to see what it is.

You probably have developed superficial thrombophlebitis in the vein in the groin. You need a follow-up venous ultrasound exam. Take Ibuprofen 600 mg three times a day for a couple of days. This will help the pain and inflammation.

It is probably an accessory vein that has thrombosed. Your doctor can check this with ultrasound.

Is your leg swollen? You need a venous ultrasound to determine what it is. Perhaps the vein that was treated is simply just "dying off." The most serious thing is to rule out any blood clot.

The most common cause of this hardness in the groin would be the saphenous vein becoming hard following the RF treatment. The vein responds to ablation by first getting hard and then soft over several weeks. The other thing it could be is a lymph node, but the vein is most common. Ibuprofen and heat will help.

I had a catheter ablation to cure my PSVT on September 5th. They burned out extra fibers that I had. My groin has healed and is not bruised anymore, but I still get a pinching feeling from my lower stomach to the groin area every now and then when I stand up. Can the catheter bruise the vein? If so, is this normal? And if this is normal, how long does it last?

After my doctor cleared me, I resumed my exercise routine, which included running, cycling, strength training, etc. I used to deeply massage tight muscles after exercise using a foam roller or a lacrosse ball and would love to go back doing it again, but I am concerned that pressure from this massage may be too much given I just had the radiofrequency occlusion procedure one month ago. Can I use these items to massage my calves, or do I risk damaging the vein or re-opening it?

I had a venous ulcer that I treated myself and it finally healed. Following that, I had a dr. perform radiofrequency ablation, which was not successful. According to the doctor, my perforator vein wiggled. Is it normal for the vein to move? If so, would that really have caused my procedure to be unsuccessful?
