I have been using AP and DTH for about 3 weeks now and about 2 weeks ago I had major cramping that started in my legs and moved up all the way through my back to my shoulders and arms! It was bad enough to where I had to miss 2 days of work and spend the whole weekend laying around. I went to the doc and he said it was a virus, the cramps ended up going away and in a little more than a week(today) it all started up again! Well I'm wondering if it is possible for AP or DTH to cause this? Also has anyone has experienced these symptoms while using either one of these? Thanks in advance
