Hi Tom,
Thought I'd post here rather than email as you would be more likely to see it while you are away.
I got Jet microchiped last monday and there is still a noticeable lump where it was inserted. You can not only feel the lump clearly but see the swelling. To explain how the lump feels, it feels like a lump caused by a needle mark, but ten times bigger. Does this sound normal to you based on the dogs you have seen who have been microchipped or should I take him back to the vet?
Cheers,
Anthony

Hi Anthony,
Sometimes there may be very minor swelling under the skin, and the microchip should feel like a grain of wheat and not a “lump”, as that is certainly not a normal result of having a microchip inserted.
From what you have posted it sounds like an inflammatory reaction has occurred, and this could be due to an allergic reaction to the microchip itself or as a result of an infection.
This certainly requires a return trip ASAP to the Vet that did the insertion, or failing that any available Veterinarian for a diagnoses of the cause and possibly antihistamines and/or antibiotics.
This type of a reaction to a subcutaneous injection of any description can leave a nasty sore that is slow to heal unless treated appropriately.
Keep in touch.
Cheers,
Tom

Hi Tom,
Can't get him in today unfortunately. I'll try tomorrow. Now that you mention it, I can feel the thing that feels like a grain of wheat. This is closer to the spine. The lump I'm referring to is a couple of cm from the microchip. On the same day he was given a C5 booster in the same area. Would it be reasonable to expect a lump to form at the injection site of the C5 vaccination and still be there after a week? He doesn't appear bothered by it but its fairly prominent.
Cheers,
Anthony

Hi Anthony,
I was not aware that a second subcutaneous injection had been given, and from what you have described it certainly now appears that the microchip is OK, and that the problem is with the immunisation booster injection.
A lump can occur with such an injection if it was not placed fully under the skin and has instead lodged in between the lower layers of skin. This then stops it from spreading under the skin as it should, and unfortunately also means that the injection will in fact have no benefit at all in regard to boosting the immunity.
I have seen a number of these and the end result invariably is a small hard lump of scar tissue under the skin that fortunately has no detrimental effect on the greyhound as far as running is concerned.
While it may not completely remove the lump caused by the injection, my initial thought is to treat the area twice daily for three days with the ultrasound, and to massage it twice daily with something like Lasonil or Hirudoid cream for the three days.
If you do this just be careful to keep the ultrasound away from the microchip, as I still do not have enough information whether the ultrasound energy will damage the microchip or not.
Cheers,
Tom
