<s>[INST] yesterday when i got up everything was fine. Later in the day when I was standing I suddenly had a severe pain on my right side lower ab area. I curled up in a ball and it subsided in about 10 min. I then had sweats and carried on with what I was doing. Then about 1/2 hr later same thing. I went home from work and layed down. The pain is less when Im laying down but when I get up it hurts. Im 45 male no prior pain. It does not hurt when I push on my stomach area. I feel like I have to go have a bowel movement but couldnt. Sine last night I did have a loose one. Any idea [/INST] Welcome to Chat Doctor .1.
