I just want to post again to say my symptoms only lasted for 18 days.
They were AWFUL while it happened. Felt like I'd swallowed glass, coughing, chills, shaking, headaches, nausea, disgusting acid reflux, sheer terror, exhaustion...
I feel ok now, about 15 days later after the symptoms improved.
I just want to thank everyone on this thread who helped me I those dark nights when the symptoms were overwhelming.
