from the description you have given for your problem you have symptomatic hemorrhoids, that is you are still bleeding despite being on medications,
i would suggest that you see a surgeon because i feel your symptoms will disappear after doing surgery on the hemorrhoids the surgery is not complex and takes just a few hours.
for the constipation
part you need to change your diet as well you need to increase your fluid intake and water intake, take fiber foods and alot of vegetables and fruits which will aid in getting normal stools which will reduce the injury
on the hemorrhoids that you have. dont strain when passing stool.
dont wear tight fitting clothes dont be in a hot place like steaming rooms for long period of time these make the hemoorhoids worse
do sitz baths that is luke warm salty water baths to reduce the soreness in your anal region.
hope have been able to answer your query.
get well soon.
you can always write back if you need any clarification.
