After triggering a long term calf-muscle injuring in my leg during a recent run, I went to my local pharmacy to get some deep heat to apply to it whilst waiting for the doctors to squeeze me in.
However, both deep-heat and deep-freeze were available for purchase; both offering seemingly the same promise of easing muscle soreness and I wasn't sure which one was best to apply in this situation.
Is there a good rule of thumb as to whether to apply a freeze or heat solution?
I.e. is it the case that cold solutions should be applied to injuries and heat solutions are merely there to relax sore/ aching (but un-injured) muscles (or something similar?)
