What are painful lumps near my horse's rear causing walking issues?

Based on your description it sounds like Colin may have suffered a puncture wound with something in his rear end. The lump you are seeing could either be some purulent fluid building up inside, or it could be a foreign object that is still inside (whatever it was that caused the puncture). If you are feeling significant amounts of heat emanating from the affected area, it is likely there is an infection brewing. The area may have to be lanced, drained, and then the horse treated with systemic antibiotics. The dragging of the left toe is hopefully not related to an ascending infection to a joint, but instead I hope it is just from a generalized pain from whatever Colin is feeling. If you have some bute or banamine around the house, I would consider using some until you can get a vet out to come and check things out. Hope this helps!

A suddenly appearing lump on the back of a horse is likely a traumatic swelling, or abscess or possibly a cyst. You should have a veterinarian examine this, as it is ikely painful and an abscess could be breaking through towards the spine. I am afraid without a photo or more detailed description it is not possible to give you a more detailed idea of what this could be and how it could be treated.

This lump on Flo could actually be an impacted anal sac, which would be painful and would cause her to lick at it. I would take her into a vet now to have it examined. The vet can determine if it is an impacted anal sac, and express it for you.

Check for bite marks (snake bite). If you cannot find any, there is likely some problem with a tooth or tooth root, or salivary gland. Your horse could also have been kicked there or, when eating, have bitten in some foreign material in the hay that could have caused a mouth injury. If the swelling does not go down within 24 hours I would call out a veterinarian for an exam of your horse's mouth and face.

Has your horse been seen by an equine vet? If not then this would be the next step. Swollen legs/veins can be a sign of heart disease. I would also have the horse tested for Equine viral arteriitis. There is a possibility that it once had this disease and these are problems connected to arteriitis. he cellulitis and the abscess can have caused sepsis which in turn caused heart problems. So these are two diseases that definitely need to be checked by an equine vet. There are a few other diseases that could cause swollen blood vessels, so your vet may want to take some blood for checking organ function as well.

Hi, sorry to hear that Chimey is in pain. One thing you need to consider is that dogs don’t suffer with haemorrhoids like humans. They can have different conditions affecting the area. They can suffer with impacted anal glands and these can be treated medically up to a certain point. They can also have tumours in the same area, some are benign tumours, other malignant. I would therefore recommend that Chimey is examined by a vet in order to make the correct diagnosis and have the necessary treatment. All the best, thank you for using Petco Pet Education Center, formerly Petcoach.

Your dog may have infected or impacted anal glands. This certainly would explain the discomfort and foul smell. I recommend getting him seen by your vet as soon as possible to have them checked to make sure that is indeed what is going on, expressed and maybe put on antibiotics to help him heal faster.
