Hello
You are taking Rcinex 600 mg and benadone (
pyridoxine) , for joint pain , doctor added pain killers .
After the use of pain killers , frequency of stool increases with chest bruning sensation .
You didn't mention the name of pain killers but most of NSAIDs ( pain killers ) causes hyper acidity or
gastritis ( this causes burning sensation in the chest , as you are having ) .
When such case visit with such burning sensation I advise them to take some
antacid , but if there is severe burning , you may need drugs like pantaprazole -d once or twice in day on empty stomach .
Now you are advised Rcinex , so both these drugs ,you can take on empty stomach and it will help in chest burning.
Now about stool , if motion or consistency is semi solid or hard need not to take any treatment but if
loose motion consult your treating doctor and get his opinion.
However , some times curd ,
lactobacillus also help in stool frequency.
Good luck.
