Is this really all down to my anxiety or something else

Really hope some 1 here can help me out with this. For the past 6 weeks ive had really bad pain moving around my back, about a week later pain in my breast bone started where it feels so painful and bruised, even hurts if i carry something and to top it off a few days after that my acid reflux became bad and feeling very breathless. In january i had a real bad bout of ibs but calmed down around march. My doc has said its down to my anxiety which has caused me to breath different causing trapped wind in back and chest and my anxiety kicking off the other things. Ive had bloods and things and all come back clear. My ibs is still playing up a little but now it hurts under my breasts and around my sides under arm pits and so on. Pain calms down when i lie in bed and the breathless feeling goes, but as soon as i get up or sitting down wham its all there again. Really having trouble believing my doctor, Does any 1 else get these pains and what are they xx

Bed! I'v had a touch of ibs most of my life! 1 or 2 flare up a year! Lately 24 hrs a day, sometimes in bed at night the pain due to wind!!!!! My whole stomach and back is in permanent spasms! Loose 1 day, solid another day, no appetite, use to love my food. Fasting is not the answer as empty stomach means gas.

Should start Bev!!!!!!
