At least a few times a day, patients ask me about whether they should be using ice or heat to help relieve their back pain. It’s a good question, and unfortunately, if you asked 10 doctors, you might get 10 different explanations for why one is better than the other.
There is only one steadfast rule regarding ice & heat: For the first 48 hours immediately following an injury, ice is better. Ice causes some vasoconstriction (the reduction in the diameter of the blood vessels) in the area being treated, helping to reduce swelling and promote healing. It also can partially numb the area for a short time, providing some pain relief.
In this doctor’s opinion, after the first 48 hours, it boils down to a matter of personal preference. Ice provides some of the pain relieving benefits, but heat can help to relax tense muscles- so there are potential benefits to either. Personally, my muscles recoil from cold and send me right into spasm, so I cannot really tolerate ice- so for me it’s heat, but I hear the opposite from plenty of people as well.
The one recommendation I will make here is to limit the time of either. If you are using ice, wrap your bag of ice in a thin towel or napkin so the cold gets applied gradually, and without ‘shock.’ Apply for 20 minutes on, 20 minutes off. With heat, the timing is not as critical, but prolonged heat can cause too much relaxation to the area, will cause vasodilation (an increase in the diameter of the blood vessels in the injured area,) and if there is still some underlying inflammation- could increase swelling. So 20 on and 20 off here is probably a good rule as well.
Hope this helps!
Insurance nightmares…
Last week, I asked you to share with me some of your health insurance nightmares. My wife and I have been dealing with a pretty complicated problem, which thankfully seems to be largely resolving. I am amazed by how many of you have had serious issues with your health insurance. I am preparing a piece or two on this topic- not strictly a back pain thing, but I felt important enough to discuss here on BackWords. Check back.
As always, thanks for visiting,
Andy
