If the horse has been worked in heat, like lunging yesterday, I cooled him out normally, used the warm water first and then sponged him off with cold water (hose cold) with liniment added. Just as I finished with the liniment bath he started trembling all over. He was walking fine, no sign of discomfort, was alert and "normal" and after a few minutes of walking around the trembling stopped…it was 90 degrees out yesterday so I would never imagine a horse getting so cold from a quick cool sponge down or even cool water hose down would cause trembling due to cold. I will add that in both cases where I gave him the secondary liniment bath he had this same trembling.
I have never heard of a liniment bath causing any type of allergic reaction (only word I can think of) and it could just be coincidence.
Taking him from very hot to very cold even with the warm shower in between might just be enought to 'chill' him momentarily especially as he is fine very soon afterwards once his outer body temperature is back to normal. You could try experimenting on yourself by jumping into a cold shower straight after getting hot and sweaty to see if it has the same effect on you - not meant to be sarcastic but it happens to me!!
