If you are experiencing pain, do not ignore this! it is your bodies way of telling you something is going on.
First thing you should do is change up your routines to avoid aggravating the problem.
Second thing you should do, if the first does not work, is to not continually increase the weight. Instead, change how you do the movement. If you slow down and focus on full ROM, almost moving in slow motion, you can actually decrease the weight without increasing the reps too much. This will help prevent additional injury.
If neither of these things work, you may consider TB500 aka "the healing peptide". Even if you decide to go down this route, and heal, you should NOT continue the same routines the say way you performed them else you will just reinjure. Be smart and remember to listen to your body.
You can read about TB500 in my log here:
