Where it is essential you seek ICE in the first instance (the acute and sub acute stage needs to stem the flow of blood, whereas heat exacerbates the situation), with chronic pain, particularly herniated / impinged disc pain, the warmth of a (protected) hot water bottle on the back, is actually quite alleviating.
But it’s not always practical to walk around with a hot
water bottle, is it? So companies have started developing heat patches you can
stick to your skin so that you can carry on with your day.
I went ahead and tested 2 current leading patches; Thermacare
Heatwraps (£5.99 for a 2 pack) and Voltarol Thermal Patch (£2.89 for a 2 pack).
There are other labels on the market which I have yet to try.
ThermaCare Heatwraps
The pack I purchased was for the lower back and hip area.
However, they have a range to ensure they mould to appropriate parts of the
body, shoulders, knees etc).
The whole shape has been well thought through with
individual little pockets of the heating element (iron) as well as the actual
material which sticks to your skin, and is very flexible. Therefore the whole
wrap envelops your contours and moves with you. You also feel the heat begin as
soon as you place this against your skin. It states you can have up to 16 hours
wearing it, but this thing kept emitting heat for a further 24 hours sat in my
waste paper basket after use! I was very
impressed and therefore, although if you were to use them daily, it could be
seen as costly. However, it was a great aid when I needed to be out and about.
Voltarol Thermal Patches
These were far less impressive.
From peeling it and having it stuck against my back, within
2 minutes the pack was already un-sticking itself (peeling at the edges) and
was yet to warm up. I’d also given it a fair old shake up (like a ‘sweet n low’
as I tried to shake the iron powder into the corners of the packs so that the
correct part of my body would actually benefit from this. From a brief visit to
the shops, the pad had already completely unstuck itself and fell down on the
floor and it never did really warm up. I was just ‘aware’ of a vague chemical
reaction having taken place. I would
have been better Pritt-sticking 2 sugar packets against my back for all the
good it did!
Not flexible, unable to adhere to your movements and
contours, barely warm and useless shape, covering minimum area. Even though
this item is cheaper than the ThermaCare wraps, it didn’t deliver on any level:
I will certainly NOT be purchasing this item again. A complete waste of time
and money.
Conclusion: Buy
ThermaCare Heat Wraps if you need therapeutic heat whilst on the move.
