I ran a 3 mile mud course race on a cold September day I was feeling great and in great condition. Immediately after the race my lips and nails turned blue and my symptoms continued to get worse. I do not know if my symptoms for the last four months have anything to do with the race. However, everyday after that I felt more and more nauseous, extreme brain fog, my back starts getting a tight feeling, I feel like I am unable to take a full breath as my chest feels like it is being squeezed, my nails turn blue and I feel uncomfortable in my own skin. I lost 15 pounds in the first 3 weeks and have not gained the weight back and I have not been able to exercise since (I was exercising 3 to 4 times a week before the race). I don't have diarrhea or constipation but my bowels seem lazy. I have loose stool but its hard to go. I've been tested for EVERYTHING. Went to a GI and told me it was IBS over the phone after his colleague told me in the office the day before he didn't think it was GI related. The Neurologist told me they did not think it was related and I have been seeing a Rheumatologist for the past month who has also run all blood work, X-Ray, CT Scan, MRI and they still do not have any answers. Overall, the brain fog, tight chest and breathing, exhaustion and GI discomfort are consistent and severe. Do you have any suggestions or ideas?
