I was constipated for 4days used a stool softener then had to go to bathroom 5 hrs later had bad stomach cramps it took about 30 minutes sitting toilet before I went. this morning when I went to bathroom I had pink colored blood on toile tissue an some in the toilet. about 4hours later I started passing gas and had light colored blood on my underwear and on toilet paper. would the medicine I have been taken cause all this to happen. Meds are doxycycline 100mg,methylprednisolone for six days and also hydrocodone 7.5/325 and also Plavix.
