Pet Health > What is a disease in rabbits with the abbreviation EC stand for? > Rabbit Questions

My rabbit is 12 years old and I found a rabbit support website and I wrote someone about what was going on with the health od my rabbit and someone wrot eme and asked if I had him tested for EC. I have no idea what EC stands for. I have copied and pasted the contents of the letter I sent to the other person so you could see what symptoms I gave to her. I hope you can help. There is also a medication she mentioned in there called metacam, do you know what that is too?
Thank you in advance for your help.
Sincerely, Trish

Letter to person ---------------------

I have a question or 2. I have a 12 year old black Netherland Dwarf rabbit named Chompers (named because for years he would chomp on whatever he could get his little mouth on). He is the sweetest little one that gives kisses everyday no matter how bad a day he is having. Something happened about 2 months ago where he lost the use of his hind legs. I don't know if he had a stroke (if bunnies even have these, actually I have learned a wealth of information about rabbits after reading your web page). I did as your page advices and that was to shave the back area to prevent urine irritation and I apply either AD ointment or something like that several times a day to act as a barrier so that the urine cant' get to his skin. I give him a full bath about twice a week and a cleaning of the back end and soiled parts everyday. I always put the protective ointment every time I clean him. It also seems as though his front legs are starting to bend in ways that I know they shouldn't be. Please don't get me wrong and invision me as some kind of beast that allows pets to suffer. He is eating more than ever, all kinds of things, still drinking, grooms himself the best he can in light of his legs difficulties and he does pull himself around with his front legs. I have noticed one thing with him and that is his extremely sensitive ears. Sometimes they get very very red (at times a tinge of blue) and you can tell that when you touch him it hurts him because he jerks away. I try not to touch them but I do have to clean them and make sure that with his squirming around him cage (which I have lined totally with towels, water proof pads, and those puppy training pads, and a heating pad which is under many layers of material so he does not get burned in any way. I only put it on at night because his little back legs get so very cold.) he doesn't have poop or urine stuck on the ears or in them. All his life his ears were never sensitive, I have no idea what is going on with them. I also notice that he has muscle spasms in his back legs at times and they shake a lot, but if you put your hand on them they do stop shaking. I am well aware of what signs to look for to determine when it may be time to let him go on to the rainbow bridge to be with our other beloved furry family members. Since he is still moving around, eating and not sleeping all the time I just can't bring myself to do it now, am I wrong? Do you have any suggestions or links that you know of that I can go to find out a bit more on the senior rabbit and what I can be doing to make his last days or months a bit better? Any input that you can give me would be greatly appreciated. I look forward to hearing from you. Take care and have a good one.
