Guys. I injected my left bicep for the very 1st time on Thursday. Everything was sterile and I did nothing different to how I normally inject my shoulders. Thing is,,,later that day I started to get pain, not only at the injection site itself, but the whole bicep radiating below the elbow!!! The following day and now my bicep is agony! I can remember the first couple of times I injected my delts,,I couldnt raise my arms or even sleep on the same side for days and days cos it was so painful! Im kinda hoping its just yhe same problem! There is reddening to the surface skin but seriously,,,the pain is intense! What do you guys think?? Thanks
