Once again I must say that I am very sorry to hear about the death of your husband. As a lupus patient we never like to hear when someone dies. However, that is the harsh reality of the sickness. I too suffer from blood clots. I was rushed to the hospital with severe pain in my lung area but the doctors did not realize I had a blood clot at the time. However, further testing showed I indeed had one. I have been on blood thinners ever since and my doctor told me I will be on them for life. I hope your husbands doctor had put him on thinners.
If your son is taking blood thinner then yes you need to be careful with him having cuts. I am really very sorry to hear that your son at such a tender age has to deal with this ordeal and I really wish you all the best.
How old was your husband when he died?
Please try to hang in there and make prayer a part of your day to day activity. Bye for now. Please reply if you can.
