This may be all that happens; however in some cases tingling type of pain may persist for one to four weeks, as the nerve heals. This is inconvenient and may be unpleasant but it eventually heals up. Another rare complication is for a small clot or thrombus to form in the vein at the site where the needle was inserted. This is noticeable as a small firm lump just under the skin.
The lump may or may not be tender and will go away over a couple of weeks. Finally, there is the possibility of infection developing at the site of the needle puncture. This is extremely rare and would be noticed as developing redness and pain. Most times, discolouration and tenderness around the needle puncture site are the result of bruises that are healing but if you are worried contact the person or clinic where you had the blood collection done or visit your doctor.
Finger-pricks A small number of blood tests require just a finger-prick. A very small sample of blood from your capillaries can be obtained from the fingertip or earlobe, or from the heel or big toe of a newborn baby. Warming the skin with moist, hot compresses for about 10 minutes helps blood flow to the area.
The skin is then pricked with a lancet. Because there are more nerves in the finger than in your elbow, you may find that a finger-prick is a bit more painful than venipuncture even though it can seem less intimidating. Arterial samples In more critical situations patients admitted into hospital may require blood to be taken from arteries.
This procedure, known as an arterial sample, is performed by a doctor or specially trained nurse. A local anaesthetic may be administered and afterwards the nurse applies pressure to stop the bleeding and prevent bruising. Warning Don't risk using unapproved coronavirus test kits More Info.
