Hi, i'm not sure if this is the right place to write this, but I really need help! We tried a new saddle on my horse because her old one doesn't fit. I rode in it for maybe 30 minutes, then the next day I felt that she had lots of lumps on her back. I carried on using the saddle for 2 more days as I felt that the saddle couldn't have done that to her back so quickly, they came up very fast and were very hard. Then I decided to stop using the saddle and wait for the lumps to clear up. I haven't ridden her for 9 days yet the lumps haven't gone down yet. Does anyone have any idea what could be wrong?
