On 12 FEB 2021 I received my first dosage of the Moderna COVID 19 Vaccine, Lot 016M20A. On the day of the vaccination, the pain from Psoriatic Arthritis  (primarily bi-lateral feet was low in comparison to the average level of pain over the last 7 days).  There was also discomfort in the hips which for time to time had presented with point pain at the connection of the hip to the Femur. BLUF: Most significant joint/muscoskeletal pain related to exacerbation locations for Psoriatic Arthritis that I have ever endured since receiving the injection.  Prepared for second vaccination, but fearful of PSA not being in control and dramatic escalation in discomfort in feet and hips, affecting ability to walk.  I received my vaccination at some time after 1400 hours, 12 FEB.  No issues noted until approximately 2300 hours, 12 FEB, when significant and debilitating pain was noted in multiple joints or areas affected by recent Psoriatic Arthritis exacerbations.   Initial Pain made it difficult to sleep from the 12th into the 13th due to significant discomfort. Through that first night, the pain immediately flared, bilateral feet, left and right hip and point pain at three locations on veterbrae, (lower, mid and upper back).  Pain was most pronounced in feet and left hip,  the feet (all toes seemed to throb in pain and were sensitive to touch or simple movements).  Pain in feet and left hip was a 10/10.  Left hip pain was slightly different than the point pain and seemed to radiate out from the area where it connects to the femur. 13 FEB: By 0815 on 13 FEB the pain in the right foot and right hip decreased, as well as the pain in the lower, mid and upper back but the pain in the left foot and left hip continued, slightly less strong than the night prior.  Pain level decreased to 8/10 for left foot and hip and was down to a 5/10 for the right foot and hip and a 3/10 for the areas on the back. In the evening of 13 FEB it was noted that the pain in the left hip became more generalize:d vice the specific point pain that I have witnessed off/on since SEP 2020.  Continued to note evening pain that felt like burning/tingling pain on both feet.  At this point the pain in the evenings appeared to be worse than the AM pain.   Left Foot: 9/10 Fight foot: 7/10 Left and right hips generalized pain: 6/10 Lower, mid and upperback: 5/10 It should be noted, that left shoulder discomfort from the injection never exceed 2/10 as it appeared 24 hours after the injection.  More pain in shoulder associated with mobility/rotation? I lacked the ability to simply walk through the house due to the pain throughout the past 36 hours.   14 FEB: Less discomfort in AM, but still greatest in left foot. Left Foot: 7/10 Fight foot: 4/10 Left and right hips generalized pain: 3/10 Lower, mid and upperback: 4/10 PM:  Significant increase in pain at bed time. Left Foot: 9/10 Fight foot: 7/10 Left and right hips generalized pain: 6/10 Lower, mid and upperback: 5/10 15 FEB: AM: continued lessening of pain/discomfort in AM, but appeared back throughout the day, worsening at evening.  Pain in left hip was noted to be much more pronounced shooting out in multiple directions, to include causing discomfort from the rear of the hip, and when seated shooting pain in the direction of my inner thigh from the back of my hip.  Pain in feet continues to be like a burning/tingling pain in the evening, most pronounced in 2nd and 3rd toes on my left foot and big toe and little toe on my right foot.  The pain also appears to be much greater at evening than in AM. Left Foot: 9/10 Fight foot: 7/10 Left and right hips generalized pain: Left Hip 8/10 right hip 6/10 Lower, mid and upperback: 5/10-not much change-very point specific pain.. I am not witnessing fatigue or any other problems other than joint/musco skeletal pain.  I have also not been getting shooting pain in feet that has appeared from time to time which feels like someone hammering nails into individual toes or shots of violent pain, only a sustained burning/tingling pain. four days later the Psoriatic Arthritis locations continue to rage following the vaccine, most notably bilateral feet and left hip, where the pain in the hip appears to be radiating in multiple directions.
