I am facing this middle abdomen pain 5cm above navel for the past 3 months. Took abdomen ultrasound which came back normal. My Doctor gave me vitamin tablets and Probiotics for 2 month thought it is due to stress. But now when I look back I think that it is due to I could have ate cat hair/ allergic to my cat. There is a cat in our apartment which ibused to rub and feed her everyday and the cat used to caress me. Later I noticed that whenever it caressed me there are lots of hair stick to my track pants with which I used to sleep and eat regularly. This make me to realize that maybe my middle abdomen pain is either due to allergy towards cats or I could have ate the hair of the cat unknowingly all these days. Can you pls advise me?
