I just got a diagnose of myofascial pain syndrome in addition to POTS , but after seeing a PT it seems like the diagnose doesn't cover all of the symptoms - mainly because of spasticity. I was wonder if anyone here suffer from muscle weakness in the legs [i walk with crutches], pain - mostly at the calf, difficulty keeping the body and neck upright, numbness of the feet and stiffness. All in addition to POTS. It doesn't seem to be Chiari, Myasthenia gravis or Lupus. I had a brain MRI 10 months ago and there was no evidence of MS and my EMG came normal. If you have experience anything like that - I will be very thankful to hear what it might be - In the mean time it becomes harder for me to walk and do daily activities. It seems like the doctors that I see getting a very hard time to separate which symptoms are POTS related and which are something else.
