Investagate symptoms and conditions

I have been taking nexium for about 3 months and I decided to stop due to the development of severe pain in my heels, hip, shoulder, collar bone, and hands. Now looking for a natural way to heal my ulcers. I was told aloe vera liquid. Not sure about this so I will investagate.

Been on warfarin about 3 weeks due to an a-fib condition.. Dose is 2.5mg a day. Since starting I cannot sleep, feel very tired and fatigued and slight sour stomach. Doctors say this is due to the a-fib but I don't think so. All I hear from my doctors is no side effects. Hs anyone else experienced these symptoms, and/or is there a website where I can find some answers.
