Covid19 Adverse side effects after receiving 3rd booster shot:  I am a 64 year old male. I am reporting a serious adverse side effect after receiving a third booster shot. I previously had made an earlier attempt to file this complaint but my online form was stopped and rejected after 20 minutes. I find this a bad policy by the CDC and it should be corrected.  Detail of incident:   My first Covid vaccine was 4/26/21 with the J&J (Lot #1808980)  I experienced no adverse side effects. My second shot (booster) was 10/27/21 with the Moderna (Lot#023F21A or 032F21A) I experienced mild (fatigue, flu like symptoms) for about 36 hours after injection. Then nothing further.  My third booster was 6/13/22 with Moderna (Lot#059A22A) I experienced injection site soreness later the same day and the following day only because the shot was administered closer to the interior of my left upper shoulder, and higher up on my brachii biceps. The soreness dissipated within 2-3 days. However, about 5 days since receiving that booster shot I started having pain in my left wrist, palm, and fingers. (pain, numbness and loss of grip strength) I regularly bicycle for exercise and good health and had not experienced any pain or diminished grip strength ever prior to this date. I decided to monitor the pain and continue daily rides. After several more days the symptoms only got worse and bicycling seems to aggravate the pain, numbness and lack of strength.  I tried a number of OTC topical pain relief products, but none were of any effect to reduce the pain. Further the wrist/hand was much more painful in the morning after sleeping. Additionally, there developed a correlation of soreness/numbness at my elbow area and the interior shoulder area where the nerves pass through. I thought that the lost of grip strength and the pain when using the left hand warranted a visit to the doctor. Unfortunately, its almost impossible to see a doctor immediately and I had to wait about 2 weeks before getting seen. In the interim I continued to try topical pain relief, with no further effect, physical massage, chiropractic, and acupuncture to see if this would relieve or resolve the wrist/hand pain and weakness. None were successful other than temporally/nominal reduction in pain. I spoke to all of these health care workers that the pain in the left wrist/hand developed within days of receiving the Covid19 booster shot. I was hoping that they knew of any connection between the shot and the problem. None had any information to offer or an explanation as to how the problem may have developed, nor a cause for recovery.  The CDC public website  list ?known adverse side effects?, and one that is listed is Guillain-Barré Syndrome (GBS).    It specifically notes ?men over 50? and  ?having received the J&J?. Which in my case I am over 50 and received the J&J.  I have not suffered any  injury to my left arm/hand. The only recent cause and effect was getting the booster and then shortly there after developing hand/wrist pains, which according to the Doctor after being examined; were caused by nerves, not muscle or bone damage. The medical facility (a very large hospital) doctor knew little about Covid19 side effects and dismissed my concerns and offered no follow up.  Which is why I am filing this complaint approximately 4 months after the last shot. The physical problem has not cleared up on its own and has gotten to the point where I can not  grasp and close my left hand and fingers.    This is very troubling to someone who uses their hands as an artist. I request a response to my filing this complaint and sincerely hope that there is a medical remedy available. I can be reached at any of the  following contact points.  I could use any and all help that you can offer.  Thank you.
