Hi..it can cause a lot of muscle problems aswell..Aparentlly vit D is very important for the neuro muscoskeletical system..I see a reumatologist ,she didin t think i have fybromialgia ,because i don t have the specific pain areas, and i don t feel extra pain on pressure...also the pain is not severe..About the post exortional malaise..this is probably the only one thing that separate Cfs than other diseases,but is so vague,i don treally know what ''malaise '' mean..i do feel tired the next day after exortion..but is not this the same for everyone?? It's not a dramatic change in the way i feel..Does PEM means you are are bed ridden ,like with a nasty flu ?
Another important thing to make clear is that Post Exertional Malaise (PEM) is not only caused by physical exertion. It is caused by physical, cognitive and emotional exertion. This is why some severely ill ME/CFS patients cannot tolerate any light, sound, speaking, etc. For those things cause them to experience have PEM ("crash"). With ME/CFS not only does the lack of energy limit what you can do, but also PEM limits what you can do. For example even if I feel like I do have the energy to have dinner at the neighbors house I know I cannot because it will cause me to have PEM afterwards. In my case because of PEM I am not almost totally housebound, bed/recliner chair bound. I want to do things, see friends, cook meals, and so forth but I can't because it will make me much sicker afterwards.
An example of how emotional exertion triggered PEM in me is when some months ago my husband and I saw a deer fawn in our driveway with a horribly broken leg. I immediately got emotionally upset and began crying and 30 minutes later I "crashed" hard into PEM. The emotional exertion of the experience pushed me over my body's limit for exertion. Also while many people's PEM does not come on until a day or 2 later after the triggering exertion, for me PEM often comes on rather quickly sometimes and other times it take a few days for it to hit me.
For me Post Exertional Malaise is not subtle. Before i was diagnosed with ME/CFS I had actually been describing PEM almost to a T to the various doctors I saw, but none seemed to have any thing to say about it. When I discovered the term" Post Exertional Malaise" and saw it's definition it was a lightbulb moment and I instantly knew this is what I was experiencing. PEM for me is unlike anything I have ever experienced physically in my life. It is nothing like "fatigue". I've often described it as "feeling like I've been hit by a Mack truck". I actually came across another person who had posted the same description.
Here are a few other descriptions for PEM that other ME/CFS'ers have posted. I relate to their descriptions of it.
"What does your PEM feels like:
I get the feeling that trying to think is literally ripping my brain apart from the inside out. There's extreme discomfort up my spine from mid-back, and all around my head. Not exactly "painful" in the conventional sense, but agonizing in a whole new way. Processing somebody talking to me feels like every word is going to fry my brain. This kind of sensation tends to happen without the delayed reaction, though, so I'm not sure whether it qualifies as PEM. It's the consequence if I try to "push through" once things are already difficult. It is awful.
I also get a different type of PEM from physical activities or stress. Feels like a really supremely terrible cold, except without the congestion. The glands in my neck swell up like mad, and I feel super crappy/ill. Super low energy, even compared to normal. Super weak - walking up one stair becomes a challenge. Not capable of even attempting mental activities. Can't do much of anything at all beyond lying there waiting for it to go away."
here is another...
"What does your PEM feels like:
An increase in ME symptoms. For me that sore throats, glands, sore muscles and other flu type symptoms. My brain stops working and I am very physically weak."
