I had a treadmill test (exercise echocardiogram) done at my cardiologists office three days ago and have been in severe physical pain ever since. I am not having fatigue, PEM, or anything I expected but the muscle pain is unbearable at times. To give a tiny bit of background, in 2010, I had a severe injury to the tendon in my right arm due to taking Levaquin (this was pre-CFS.) It took me a year and a half to regain functioning in my right arm and it has never regained it's full strength. In the treadmill test, I had to grip the bar really forcefully as they increased the speed and incline of the treadmill and my right arm was in severe pain (but if I let go, I was afraid of falling off!) Ever since the test, my right arm is practically numb and very weak. My upper muscles (shoulder, neck and jaw) are overcompensating for my arm adding to the pain. I literally cannot grip anything or write with a pen or open bottles, etc, and doing everything with my left arm. I am also having pain and spasms in my calves, pain in thighs, right hip, back and feel as if the entire right side of my body is out of alignment. I am going to call my chiropractor tomorrow to see if I can get a same day appt to see him and also try to get a massage. I have been taking extra electrolytes, using heating pad & ice, and taking painkillers that I normally only take for severe menstrual cramps but they are barely helping. Pain is normally not a big issue for me so I don't know any of the other techniques!!!
