And I assumed I had all the symptoms of COVID. It is just to be expected running a fever, body aches, runny nose, nauseous, I didn't lose my sense of taste and smell but I have all the symptoms for a cold, that went away, about four days I was fine. But, the problem is that excruciating pain from that night that I woke up, I've been getting it for 2 to 3 times a week. It like I want to cut my arm off, it's so painful. and it's like it runs from my left top of my left shoulder right to my forearm and the exact thing it hurts, I've never injured my left arm ever. the pain is just so hard to describe, it just, it hurts so and it brings me to tears. It has been going on for the last man I was like,' okay, what is going on' I can go two or three days, I'm fine, wake from my sleep and it's the same thing, and it's like 'what the heck.'.

Caller said that she is no longer having any other side effects aside from this pain as if it has been a regular. Caller wants to know if is this a still a side effect of the vaccine.

She also wants to know how long this pain in her left forearm can last.
