Day 17. Shoulder pains

Yes, I am hanging on for dear life! I am enjoying the journey, its quiet exciting, so many different pains & problems all happening;-) Shoulders still really hurt, like knifes right between the shoulder blades, ouch, and I still have flu like symptoms too. And bowels dried up today as well. water intake is 3-4 liters per days at the moment. Any suggestions for BM's? Salt water flush? Epsom salt flush? Enema? Bigmac & fries?
