Hi Neurologists Dr Michael Hanna or Dr Abhijit Chaudhuri Immunologists Dr Vanya Gant or Dr. William Weir I received HEPATITIS B VACCINE on my left shoulder about five years ago; back then I was a regular at GYM- used to lift 100 pounds without much unease; used to do treadmill walking without getting exhausted; no persistent pain anywhere in the body. Post vaccination, I started experiencing various ACHES AND PAIN - started with left shoulder pain spontaneously (just the left not the right) making me unable to lift even half the weights i.e. 50 pounds (used to lift 100 pounds earlier). Thereafter series of unexplained pain started; my toes began to hurt while walking - sometimes left and sometimes right. The pain isn’t there at rest. I am sure it is not due to shoes, as the pain occurs irrespective of the type of shoes I wear. Following the vaccination, there is also perceivable significant LOSS IN STAMINA; I experience breathlessness in the initial phase of walking on the treadmill - earlier I used to walk on treadmill for quite some time with ease. I have muscle spasms, and joint pains (without inflammation) in random parts of my body. There is persistent feeling of fatigue; exhaustion which does not alleviate with rest. Also, my sleep is affected, I wake up feeling unrefreshed and am unable to concentrate in my daily activities. Also, to add on, there is a continous pain that I experience in my LEFT UPPER ABDOMEN in a specific area whilst sitting. Hence I feel very uncomfortable whenever I am seated on a chair or a couch, or in the bus. The pain I perceive is connected to posture and a change in the same eliminates it; which makes me feel that it is muscular in origin. There is no abdominal pain when I am standing or lying down. No pain medicines have helped so far. I am sure the cause does not lie in the digestive tract i.e. stomach, small intestines or large intestines as I don’t have any indigestion problem... my appetite is just fine, I eat well and at proper times. To summarise my agony- I was absolutely alright and pain free 4-years ago; before I received the HEPATITIS B VACCINE, used to work out regularly. But now, I am left debilitated, feel tired all the time. What I've done so far. Had 14 blood tests including Rheumatology blood tests all the 14 blood test came back fine. I did Ultrasound which showed Hepatic Steatosis and the rest of the organs were of 'normal appearance'. Thanks to all that respond!
