My doctor says he needs to add epinephrine to the numbing solution he is going to inject when he does the RFA procedure. Is that really necessary?

Can't he do it with just simple lidocaine?

Epinephrine is a vasoconstrictor mixed with lidocaine to minimize bruising. Straight lidocaine injection is an option, too.

Standard tumescent solution includes epinephrine for maximum effectiveness. For special cases, it can be omitted.

Yes, you can. The epinephrine is to decrease bleeding and it's optional.

The addition of epinephrine to the numbing solution is entirely a matter of preference. Your doc must like to have it in the numbing solution. I typically go without it since some patients react adversely to the epinephrine in the liquid. So to answer your question, the epi is not necessary. I do those procedures all the time without it and my patients do fine.

The solution is very diluted, so people usually have no problem with it. It can be done without epinephrine but does not work quite as well.

No, it is not necessary. I have not used that in over 10 years for my ablation procedures.

The procedure is best done with a small amount of epinephrine to help with the local anesthetic and vasoconstriction.

The reason for epinephrine is to cause constriction to reduce bleeding and to prolong the effects and duration of the lidocaine. However, the procedure can be done without epinephrine, and I have many times not used it if the patient is allergic to it or afraid to have it.

I had RF ablation 2 years ago, followed with 2 treatments of sclerotherapy. After the procedures, I was pain-free for 2 years. 3 months ago, however, the pain came back. It's constant and in the other leg. Went back to doctor and had ultrasound, which showed no blood clots and great circulation. They did say I had a tiny varicose vein in one leg and reflux in the other newly hurting leg. When I saw the doctor, all he said he could do was sclerotherapy, which might help with the pain.

Three weeks after having a greater saphenous vein ablation and phlebectomy of my right leg, I am now having painful muscle spasms in my posterior calf muscle, just below the calf midline. Dorsiflexion of the foot helps alleviate the spasms. Doppler studies show no DVT and indicates the vein was ablated in its entirety. The pain is very much like the pain I experienced prior to the surgery, except more frequent. My doc seems to think everything is fine. Should I be concerned and what would help?

I have a vein on the inside of my calf that bulges after exercise. An ultrasound found that I have reflux of 7. I don't have heaviness or swelling or other symptoms, just the one varicose vein. The doctor wants to do RFA and foam sclerotherapy. Is it better to have the RFA, or just get the one vein taken care of then see if I develop other symptoms later? How likely are future problems vs how big a deal is ablation? I guess I am asking if the RFA is really necessary/worth it.

The incisions around my knee area feel hot and hard, but there don't seem to be any other signs that would lead my to think they are infected. The incisions are almost fully healed and there's no redness that isn't linked to my bruising, no pus oozing, and no fever. I just noticed today that they feel hotter than the same area on my other leg, and can't see my regular doctor until Friday. So, I'm just wondering if this should be evaluated earlier, or if it's OK to wait until Friday.

I was diagnosed with venous insufficiency via an ultrasound last Oct. I have reflux of the GSV and some other veins. I constantly have heaviness and aches in my leg, but no swelling or varicose veins. Elevation, compression stockings & walking help some, but I'm still suffering. My legs feel best when I wake up in the morning due to elevation all night. I'm looking into vein ablation, but am scared of the risks. Should I be? Should I proceed with a vein ablation?

I have a couple of varicose veins, but mostly have spider veins. The spider veins have "resisted" treatment (laser) because bigger veins are causing the problem on the surface, as doctors have explained to me. By reading testimonies on EVLT, I get even more discouraged about laser treatments. I have to add that (luckily) my goal is aesthetic. Would you say radiofrequency is a better option for me?
