I am 1 month post op. Doing my walks about 10 mins morning and evening. Use the spirometer about 3 times daily. do my stretching exercises. I have suddenly been feeling pain in my chest on the left side, a pull feeling upto my shoulder and also my tricep. It just comes and goes. It does happen on the right side too but the left side makes me thinking if it is my heart. Anyone els has felt anything so? Is it normal to have that pain feeling ( the pain is a little ticklish pain). I feel its just making me paranoid. Thanks.
