The reporter is the patient.  A patient (no qualifiers provided) received bnt162b2 (BNT162B2) (Batch/Lot number: unknown) as dose 2, single for covid-19 immunisation. The patient's relevant medical history and concomitant medications were not reported. Vaccination history included: Covid-19 vaccine (1st dose, Primary Immunization series complete but unknown manufacturer), for COVID-19 Immunization. The following information was reported: BACK PAIN (non-serious), outcome "not recovered", described as "I started getting really got bad back pain and it kind of moved around, I ended up in the urgent care; still having some pain in my back"; SENSATION OF FOREIGN BODY (non-serious), outcome "recovering", described as "I feel like there is something stuck in my throat; feeling when you are nervous; feeling that you have a lump in your throat; it''s been happening off and on"; PARAESTHESIA (non-serious), outcome "not recovered", described as "it feel like it's been 'tinging', like I can still breath"; FEELING ABNORMAL (non-serious), outcome "not recovered", described as "I am not feeling like I can't breathe but I just feel like there is something"; LYMPHADENOPATHY (non-serious), outcome "not recovered", described as "Had a lymph node on my neck bulge out pretty big like half the size of the golf ball". The event "i started getting really got bad back pain and it kind of moved around, i ended up in the urgent care; still having some pain in my back" was evaluated at the emergency room visit. Therapeutic measures were taken as a result of back pain, sensation of foreign body, paraesthesia, feeling abnormal, lymphadenopathy.  Additional information: number, number and expiry date were reported as unknown. The patient received second Pfizer dose vaccine, it's been 4 weeks now and had a question if it was a side effect. So, a couple days after second dose had a lymph node on neck bulge out pretty big like half the size of the golf ball. And then doctor said no it's fine, it's just body making antibodies or whatever. And then a week about that time started getting really got bad back pain and really never ever in life had back pains and it kind of moved around. And ended up, waited for like 2 weeks and finally ended up in the urgent care and they put on some Prednisone and had one more dose of that and the patient felt better, still had some pain in back. But another side effect that the patient had was felt like there was something stuck in throat, and it was kind of like you have 'pill' stuck in your throat or you know that feeling when you are nervous and you just have a feeling that you have a lump in your throat. Wondering if that could be like a lymph node that had inside of neck, if it moved into that area of neck making it feel like it's been 'tinging', like the patient can still breath, not feeling like can't breathe but just felt like there was something stuck in throat. And it has been happening off and on, like the patient noticed it a week or more ago and then it went away and then now it's been back and it has been there last night and it also got a little better this morning. And the patient just doesn't know if it was, any of these things that felt were side effects.  No follow-up attempts are possible; information about lot/batch number cannot be obtained. No further information is expected.
