Feeling worse after day 5 and now on day 8

First day I did 250mcg. No adverse reaction although eyes did feel a little hazey.

2nd day to the 5th day, 500mcg twice a day. No adverse effects but also no improvement yet.

Day 6, no injections as I was waiting on my next order to arrive.

Day 7, 500mcg twice daily again, stil no improvement and actually questioning if my elbow tendinitis feels worse than before staring.

Day 8, had to get new syringes from the chemist, gave me different ones, and my bad, accidentally dosed 0.5mg instead of 0.05mg! So, 2.5mg instead of 500mcg! Completely newb mistake, I admit.

Googled it and it said this high dose isn't a reason to panick, should be safe, just on the higher end. Definitely felt mild face ache, pressure, low level headache though.

Woke up in the night, intense nightmares and sweating, right leg felt locked up (very strange feeling). Felt like I was dreaming even though I was awake.

Woke up hours later properly feeling ill/flu like aches, swollen gland on one side of throat, sore elbow, sore shoulder, sore ankle.

Took two ibuprofen and feel better now. Unsure whether to carry on with the bpc, insure if it was an adverse effects, or if I'm actually ill.

I'd need to redose ibuprofen again if I wad actually sick with the flu or something similar, as its been 6 hours since taking them and I don't feel anywhere near as bad now.

Yes I know I stupidly took way more than intended, but I was actually feeling like it was making my tendinitis worse for a few days before this stupid mistake, so for some reason, it's not only not working, but my golfers elbow is definitely worse since starting bpc 157, and now my shoulder also hurts...

So confused right now of what to do.
