tension headache; injection site pain; bruising on her arms and legs; tenderness at the injection site; I woke up in the middle of the night trying to catch my breath; I don't know if it was a little anxiety; This is a spontaneous report received from a non-contactable reporter(s) (Consumer or other non HCP) from medical information team for a Pfizer sponsored program. The reporter is the patient.  A 60 year-old female patient received bnt162b2 (BNT162B2) (Batch/Lot number: unknown) as dose 1, single for covid-19 immunisation. The patient's relevant medical history was not reported. The patient took concomitant medications. The following information was reported: TENSION HEADACHE (non-serious), outcome "unknown", described as "tension headache"; VACCINATION SITE PAIN (non-serious), outcome "recovered", described as "injection site pain"; CONTUSION (non-serious), outcome "not recovered", described as "bruising on her arms and legs"; VACCINATION SITE PAIN (non-serious), outcome "recovered", described as "tenderness at the injection site"; DYSPNOEA (non-serious), outcome "recovered", described as "I woke up in the middle of the night trying to catch my breath"; ANXIETY (non-serious), outcome "recovered", described as "I don't know if it was a little anxiety". Therapeutic measures were taken as a result of vaccination site pain, vaccination site pain.  Additional information: She just started developing the bruising a week after" having her first dose of Comirnaty "which was odd/baffling" as she "not on any blood thinner or anything else that would thin the blood".  She stated, "I don't know if something that's in the vaccine made me more susceptible or sensitive and its coming out as bruising".  Bruising is "only on my forearms and legs, nowhere else, which is very strange. They seem to be popping out here and there. The one is really bad".  She reports "the one on my wrist has finally went away, but that was just a tiny, red, maybe the size of a dime. It stayed red, then faded. The one on my forearm, that's the scary one, it's a deep deep purple and it's about the size of a half-dollar. It's on the injection arm, it's still purple. There was tenderness at the injection site, but no rash at the injection site. I did get a tension HA but that lasted maybe 5 days and with Tylenol, it helped. That first night... I had the vaccine in the morning, that night when I went to bed, I woke up in the middle of the night trying to catch my breath... I don't know if it was a little anxiety. I propped up my pillow, I didn't lay flat, then I was fine". Of her medical history she reports "I don't have heart problems, I don't have diabetes or anything like that, any autoimmune diseases" and that she "didn't have a fast heart beat".  Additionally, she got "A steroid shot a week prior to the first dose" when she asked her pharmacist if this could have caused a reaction the pharmacist said "no there's no interaction".  Caller thought that bruising may be a sign of blood clots. Caller stated her pharmacist confirmed "although very rare it has been reported at her pharmacy about bruising".   The lot number for bnt162b2 was not provided and will be requested during follow up.
