What Could Sore Throat With Chest Pain And Dry Eyes Suggest?

I had my 3rd Brazilianl Blowout 3 weeks ago. I got what I thought was a cold 8 days ago. My throat is sore, runny nose, chest hurts with a cough, dry eyes. My symptoms feel more like an immune problem maybe with the formaldehyde in the Brazilian Blowout. What can I do to get over this. Should I see if the product can be removed from my hair?
