My father got a heart attack in Dec, 2013.He is now 55 year old. After the 2 months of heart attack, he stopped english medicine and started using homeopathy for 4 months which in turn lead to a lv apical clot. He used warfarin for 7 months and the clot dissolved. So,he discontinued warfarin. Again a lv apical clot formed in Jan ,2017 and again he started using warfarin for 15 months (with different dosages. But the clot remained the same and did not get dissolve. As warfarin has many diet instructions he started using Dabigatran from May ,2018 to till now. But the clot is same and did not dissolve. Now the problem is from 2 months he has been suffering from headache (disappeared after a month, neck and back pain. I searched in google and found that one the major side effects from dabigatran is headache ,neck and back pains. Is it true and should be the dabigatran be discontinued? In the Neurology report it is found that not made of perineural cyst in spinal cord causing scalloping of s2 body. What does that mean exactly?
