Second Shingrix vaccination ; 8/7/19 at 12 noon Second dose: 8/7/19 Had to cancel all activities for 3 days and stayed in bed feeling weak and unable to function.   Summary of my conditions, starting after my second immunization of shingles on 8/7/19.   Before the immunization: My physical condition was excellent. I was a very active person, able to work and do any activity if needed for more than twelve hours a day. I would easily walk five miles or more a day. I took five intense exercise classes a week . Also, I would go to very active and strenuous folk-dancing one or two evenings a week for three hours at the time.  After the second immunization: After the immunization I had  very limited  energy  as well as other numerous problems. ** After the immunization all my muscles became extremely weak, I had to stay in bed for four days. I have been a basket case for the past five months. *My trainer 8/13/19  saw me; he defined my condition ?As if a truck had hit me.?   The first episode  started 10 minutes into my training session with my trainer, suddenly all my muscles collapsed during the training session. Then my left knee muscles weakened, simply by getting up from a chair my knee twisted. I was in terrible pain, I could barely walk. Had to lay down until I could go home. It took a month and a half for the pain to end. *As a result of my muscles weakening, also my back gave out. Thus, I required an MRI which revealed a new herniated disk (L3 and L4) see MRI (10/14/19)). The supposition was that the new herniated disk was a result of the muscle collapse caused by the Shingrix vaccine. *Afterword?s, I had pain when sitting and could not sit for more than 10 minutes;  this lasted for one week. Then the pain stopped. *Then I could not even walk for more than 100 ft., I was in terrible pain; lasting  for 3 weeks. Then the walking pain ended  because of my trainer: *My trainer was successful in stopping my back pain and the inability to walk by strengthening my back muscles. I also used medication for week. (see below).  * In addition, I could hardly get up from any sitting position for more than four months. Finally, after nearly five months (12/29/19) and training. I now can get up with less difficulties  from a seated position.  * In addition: After the immunization I had the following reactions and symptoms which affected me in a cyclical manner, moving from one part to another part of my body, deteriorating different parts of my body to different degrees. At times, the affected part got better, in some cases it?s still not back to normal, and other parts  of my body got worse. Unfortunately, as of today 1/8/2020, I  have not yet returned to NORMAL. A  simple walk to do shopping resulted in the following: after an hour, I had to cut it short since I felt tired and my hands got very cold, even though the rest of my body was overheated because I was dressed very warmly.  *My face color sometimes looks ?ashen?. Then it looks more normal; but as my strength diminishes, I become pale again. * For the past five months, this has prevented me from working or performing other strenuous activity. All this started after the immunization which has impacted me very dramatically. *I slept  excessively, from 11 to 16 hours a day, until the end of November. * I presently I sleep about 8 hours a day.  * But I must take many rest periods during  the day, every half hour or so. Sometimes I spend the whole day in bed. However, I still feel tired even though I need less sleep. *I have a very limited energy level and get tired very quickly. If I do simple ?housework? like washing dishes or putting things away or walking from 15 to 30 minutes, I have to rest for at least an hour. Also, if I stayed out of bed in the morning, or went out, or straightened up my home, then I had to sleep in the afternoon from 3 to 5 hours. In the evening, I would get  up for an hour or so; then back to sleep all night. As of now, 1/8/20, there has been improvement as stated above. *As of 11/15/19 my stamina was slightly improved and I started exercises. Thus, I increased the amount of work or physical exertion from half an hour to an hour doing work around the house. (See below examples.) * I get VERY COLD just sitting around or sleeping. But it gets worse if I exercise. (See below exercise.) * I lost about 10 pounds of weight since 8/7/19. Since 12/22/19 my appetite is nearly back to normal.  EXERCISE: From 11/15/19 to 12/26/19. Since 12/26/19 NO EXERCISE. *I started doing very minimal exercise for maximum of half an hour exercises three times a week.  *If I take an exercise class, or other activities which require physical effort, my body, instead acting normally to get hot and sweaty, I sometimes get VERY COLD. While walking, exercising or even sleeping, sometimes  my hands and feet get freezing and mybody gets cold. Nearly every night I have to sleep with warm socks. My condition has gotten a bit better since 12/10/19. I do feel a bit warmer and develop cold spells less often, although cold spells still occur several times a day. *I started exercising  again. The exercise had a bad effect on me: I felt dizzy twice, when walking my legs became very heavy, and I have difficulties climbing stairs. The trainer told me to immediately stop all exercise as of 12/26/19.  Therefore, I stopped even the limited exercise. * Trainer told me, ?that I am not ready to exercise, because my spine muscles need to be further strengthened, otherwise I would get a spinal injury.? He recommends only the following exercise for me right now : (A) walking and (B) swimming for a short time.  * I had to stop exercising. This is another reversal of my getting back to normal.
