It’s hard to get a good look at your left lower subclaver vein without the use of a vein monitor.
The device, a pair of needles with electrodes inserted into your skin, measures the amount of blood circulating in your veins and sends it to a computer.
If the amount changes, the vein has been overfilled, and you’ll have a better indication of the amount needed to see if the blood supply can be maintained.
However, if the vein fills up faster than you’d like, the doctor will tell you it’s time to see a specialist.
That specialist will usually order an X-ray to see what’s wrong.
If that results in a red, swollen spot, the specialist will recommend a vein replacement.
It’s not unusual for a vein to fill up before the X-rays are done.
But that’s rare.
The average time between an appointment and the vein replacement is between one and four weeks.
You can have a blood test done, but there’s no way to tell if it was a true vein replacement or a false vein replacement, says Dr. Michael Hargreaves, a cardiologist at the University of British Columbia.
When your vein does fill up, the risk of an infection or other damage is increased, and the doctor may have to perform a new vein replacement procedure.
“It’s very, very rare,” says Hargremans.
The best way to prevent a red vein is to avoid excessive sweating.
In a normal vein, your body releases excess heat to cool itself, says Haggles.
When the body gets too hot, it can become irritated and cause swelling, bruising and other complications.
But in a vein, that excess heat can also cause redness and irritation.
“You get more red and more pain if you sweat excessively,” he says.
If you have a lot of red or irritated skin, a vein specialist can help you manage your sweat.
Hargrebans recommends avoiding sweating more than 15 minutes per day.
If sweat is happening too often, you’ll need to do a little bit of extra body cooling, too.
If your vein fills with fluid, it’s also possible your doctor may want to try to remove it.
The most common cause of a red or inflamed vein is an infection, so doctors will often order an antibiotic treatment.
The antibiotic will help clear out the excess fluid and allow blood to circulate.
You’ll need a special syringe to inject the antibiotic into the vein, but you’ll be able to keep the syringe nearby during treatment.
“The needles can be placed on the top of the syringes or at the bottom,” says Dr Hargscheids.
“If the needle comes out with a black spot or a red mark on it, it probably means you haven’t properly treated the infection and that you need to be more careful.”
Another risk is a cyst that grows over time, says Michael Kowalczyk, an orthopedic surgeon in Vancouver.
You may also have cysts on the sides of your neck or chest, he says, so a doctor will need to examine you more closely.
“I’d be very concerned if I didn’t have the cyst surgically removed,” he tells News24.
In addition, if you’re using a vein that’s not properly sterilized, the needle may puncture the wall of the vein.
That can result in a blood clot.
“We recommend you wear a mask while using a tube of antibiotics,” says Kowalyk.
Another common cause is an allergic reaction, which can be triggered by certain medications or medications you take, he adds.
“Any medication that has an allergic effect on your body can cause this,” he explains.
“So, if your skin is burning and it’s coming up from underneath your mask, it could be a reaction to a drug.”
In the case of a false-vein vein replacement , the doctor won’t necessarily have to remove the vein to do the procedure, but they will need the proper instruments to perform the procedure.
You could also need to have an x-ray.
“Your doctor will usually perform an xray,” says Sargas, the Canadian Blood Services spokesman.
“There’s a lot more risk associated with an xerostomies than you might think.”
