Irritation in stomach and anus. Help.

Dear Doctor, The issue started for my mother with lose motions and mild stomach ache. Its been 15 days now the loose motions are somewhat controlled but everytime there is a feeling of pooping and the heaviness in Anus persist leading to contant irritability in complete stomach. If the feeling of pooping is there 5 times a day and she sits for peeing then those 5 time s the motions occur. Kindly assist because the condition is still prevailing since days even after a complete course of medicine for 10 days for these loose motions issue. Due to this the whole body is suffering. Also, due to Bone TB's medicines the poop was always thin but this issue started recently and is still there. It will be 2 years now in may end with TB medicines. As per we have seen her till now the issue with stomach don't seem to be related to Bone TB but with no knowledge on medical issue we require your help. Please help. Thank you a lot in advance. Kind regards, A suffering daughter
