Had a bad day yesterday, went to the bathroom as normal when I got up and felt very weak afterwards, had breakfast and my tablets, within 1/2 hour had to dash to the loo again, felt even more weak afterwards but attempted to persevere and got ready to go out, left the flat to go to the bus stop and halfway there felt that weak I could hardly walk, managed to get home and had to dive to the loo again, lay down on the sofa and went to sleep, woke up full of wind trying to burp to relieve the pressure affected my breathing and was really struggling, my chest was tight and couldn't breath properly phoned the Doctor and she said I was having a panic attack and she slowly talked me down and prescribed diazepam to calm me down, told me because of my ibs to only eat something bland for dinner, so just had some tomato soup.
She told me it was most likely a combination of a diverticulitis flare up and my copd problems combined with worry that caused me to have the attack. Thankfully seem to be a lot better today although still filling up with gas and wind as usual but it's bearable.
Sorry about the long post but wanted to get it off my chest, got to admit I was so scared yesterday, have put the diazepam in the drawer and hopefully won't need any more for quite a while
