Could You please help me and name as many possible reasons for cramps all over the body as possible?
Three days ago my horse was in paddock and suddenly got cramps all over the body so that he couldn't breathe properly and he couldn't move. Vet made him relaxing and pain killing injection but the cramps lasted for 4 hours. I can say that this vet was stupid and I was in panic. She didn't check my horse's pulse or bronchial tubes and she thinks it's muscular rupture (because the right shoulder had the worst cramp). She tells me to feed pain killers to my horse and nothing else. I think she is wrong. My horse isn't lame and has been in a good mood since the next day from the cramps. Also, horse allows me to move his legs in any direction and he doesn't seem to be hurting anywhere.
Additional information: I ride my horse regularly, 6 times a week. I am just amateur, not professional. There hasn't been great change in feeding or training practice for about 3 years. My horse has chronic cough and he coughs on rainy days. Horse has gotten all necessary vaccines and deworming. Now he's breathing normally, after the cramps coughs very often but the weather is sunny and dry. Horse is 10 years old.
I consulted one other vet also who can't visit us because of the long distance. He thought that he would look the breathing problem more carefully.
As the vet didn't check all necessary things, it is very hard to find out what happened. I hope this doesn't happen again. Can You please tell me what do You think about it and what could be the reasons for such thing.
Thank You in advance
