Be Careful with disposable heat packets

Recommended Posts

During my most recent visit with my rheumatologist he asked if I used the disposable heat packs in my shoes.


I replied "of course" (though in my slippers as I rarely get into shoes, :lol: it has been a harsh winter.)  I also mentioned that on two rare occasions they became so hot I removed them and let them expire on a heat safe surface.


He said he mentioned it because he has 2 other sclero clients with difficult ulcers on their feet due overheating disposable heat packs.


I am heeding his warning though; I am also fortunate enough at the moment to realize IF they get too hot.

Hi Kathy,


How lovely to hear from you again. :)


Thanks so much for your useful post regarding heat pads. I've never actually tried them myself, although I did purchase some for my hands awhile ago, but never got around to using them. We do have a link to Heatsock Directions in our medical pages which contains further information about them.


Certainly they should be used with caution, as I would imagine it could be easy to burn yourself without realising.


Kind regards,

Great Warning to pass on, Kathy....Thank you!


I'm REALLY glad you still have enough feeling, that you COULD sense that the heat packs were too hot (in your slippers) and took them out beFORE they could do damamge to your skin/feet!  


Funny as it may sound, there are ALOT of us who CANNOT sense hot/cold differences and really have to be cognizant of that fact!


Hugs to You!

This is such an important point you bring up! The disposable hot pads are kind of unpredictable.  Most physicians and physical therapists would recommend a controlled heat source (well functioning heating pad, hot water bottle, warm bath, parafin wax treatment) which is wrapped in a protective barrier so the heating element is not directly against the skin. Also it is usually recommended to apply heat for no more than 20 minutes (or up to 30 depending on who you ask) and if you have sensory issues to have someone else check the temperature before use.  The warmth can help soften tight tendons or spasmed muscles and reduce inflammation but it can also cause damage if one is not careful.  Thank you for bringing this potential danger to everyone's attention!

Yes, the heat packet became so hot it caused the trauma to the already compromised foot, though it might not have to someone with normal circulation as they would have sensed it and removed it.  (Then again those with normal circulation would not use them as extensively...)


So nice to hear from you and your coworkers again after awhile.  Glad you are all still here :)

I am happy to meet you!  This special place has sincere support from real people with the same or similar conditions as we have.  I am glad you have found it and joined, though sorry for the reason you are here... 


Your suggestions & insight are great!   I can (shamefully) tell you from an end user point of view that the recommended heating options are either cumbersome or too time/energy consuming so I rarely make them happen and the disposeable heat packs are so easy to tear open, shake, that I use them much more often than the others.  They are just so much easier and I would guess I am not the only one. 


Please keep in touch!,
