Hi. Several days ago I had flu like symptoms- sneezing with lots of mucus from the nose, fever, headache, etc. I also experienced difficulty inspiring upon exertion for about 6 hours on one day. I no longer have the flu but I experience violent cough with minimal mucus. I think I may have walking pneumonia but am uncertain. Also, unrelated to this, I beleieve, when I sit down, I can feel my femoral pulse speed up for a few seconds then it stops. I think it may be due to a dot but am uncertain. Can anyone help with this?
