First, it is important to know a little bit about the physiology of the body. When a muscle contracts, the end product of muscle metabolism is lactic acid, which normally gets flushed out of the body. With Fibromyalgia, there is so much muscle contraction occurring continuously, that the lactic acid is not able to be flushed out of the body and therefore starts to accumulate in the muscle belly. As lactic acid is very irritating to the muscle, the body than produces fibrous tissue to cover the lactic acid so there is no damage done to the muscle.
Now that the basic physiology is finished, here is why you flare if you do too much to fast.
When you do too much exercise too fast, you are breaking down the fibrous tissue which than frees the lactic acid causing that deep burning pain. Therefore, before starting any type of exercise, it is important to very very slowly stretch the muscles. You must start very slow and add 15 seconds or more a day. If you feel a flare, than you are doing too much and you must back down to a lesser amount of stretching.
It’s also a very good idea to drink lots of water after exercising as this helps to flush the lactic acid out of the body. No exercise drinks, just water!
Remember, go very slow and gage for yourself, if you start flaring, you’re doing too much to soon.
