About 6 weeks ago my Texel tup got this lump just behind his eye, it was causing pressure behind his eye so I lanced it, flushed it out with iodine and gave pen strep for 5 days. It healed up nicely but there was still a small lump, in the last few days it has started to cause him uncomfort again as he's grinding his teeth. This time there isn't any liquid in the lump. I have given pen strep again, can anyone recommend anything else? Thanks
