<s>[INST] I'm having a lot of gas, both ends started about a week ago.  I've been takeing flax seed for about a year.  I've been having some pain in my chest along with the gas.  I'm also on meds for my heart. I tried a nitro, it didn't seem to do much other then put me in a daze for a min. or two.  I also have much pain in joints and I need a hip joint replacement.  I had trigger finger operations for all most all my fingers, had a joint taken out of my thumb, both knee replacement.  I ride a bike and try to get five miles in a day for excerise, easier then walking. thank you  P T [/INST] Respected user, hi I evaluated your query thoroughly.* This is in relation with intestinal motility disorder associated with variety of   clinical conditions , chest pain may or may not be related with this .* Your case needs thorough clinical assessment in presence of many co morbid    conditions and detailed evaluations for final judgement but still with this   narration I recommend certain guidelines for you - take small amounts of light diet at regular intervals - diet should be balanced containing all nutrients with less of fat content- avoid oily / spicy / non vegetarian stuffs / beverages / junk foods- chew your food thoroughly- avoid sleeping for 2 hours after meals - avoid smoking / alcohol / abuse substance use in any form - avoid pain killers till possible , if needed always take with Proton pump  inhibitor- physical activity in form of body part movements ( not bike riding ) is   must in form of light exercises , walking till possible , YOGA at home- avoid stress / anxiety - regular sound sleep of 6-7 hours - in our clinic we recommend certain motility related molecules for gut   depending upon the clinical severity & supportive data of laboratory , ultrasound findings if any Hope this clears your query .Welcome for any further assistance .Thanks for using Healthcaremagic.com & giving me an opportunity to assistRegards dear take care. </s>
