Yes it can cause swelling or inflammation to occur and that adds extra pressure on the same areas of trigger points and can cause more pain or increase level of pain. You may need a antinflamatory ( nsaid) drug to ease the extra pain. Motrin cane be bought otc at most stores. Hope this helps . Wish you well and GOD bless you always.

I most certainly know that any sudden injury can cause flare ups including a fall. Get through the flare ups as best you can and back into motion as soon as possible honey. Any additional stress or pain can cause a flare up. Changes in the weather can cause a flare up as can worrying, overworking, getting over excited and such. We have to learn to keep our emotions in tack as well as our stress levels. It's really impossible but we have to do the best we can. Remember "I can do all things through Christ who strengthens me. " Much love and prayers. Lila

YES, I AM LIVING PROOF.

Abso-friggin'-lutely!
Even stepping odd a curb you didn't see.
You can wrap yourself in bubble wrap and duct tape, but you're still not safe.
Have you ever had those dreams where you feel like you missed a step somehow, and you're leg jolts. Flare.
Sorry, girlfriend.. My suggestion. Roll everywhere. =-b

It has definitely happened to me. I fell on a Tuesday of one week and the severe pain didn't start until the end of the next week. I made one visit to an urgent care center and another one to my family doctor because of this. The pain last for almost two weeks. And the pain was not even in the area I hit when I fell. But it was on the same side of my body.
