i dont believe eq caused that pain, i think the eq has made you alot stronger and you might be hurting yourself. infact theres alot to take into consideration here, your on a nice dose of test to, are you real strong, work out heavy, and intense ?? that could be factors, also how old are you ?? im 45 and thats a norm, you get use to those fucking pains, haha, their like wives, they;ll nag you constantly.
and how about training principles, you do drops, pyramiding, burn outs, your training regimen has so much to do with it, i run deca for that very reason, i feel so much better on the deca, i can actually get up in the morning w/o all the sounds, haha,
and ofcourse your diet, are you getting them fish oils in your body, omega six and oils from flax and nuts, keep in mind to cycle them too, they will thin your blood out, and testosterone does the same thing, it prevents the blood from clotting, so i try and go on and off those when im juicing it up.
try motrin therapy for two weeks, ibuprofen is a anti inflammatory, it may help, thats my 2-cents 4-ya, you could of injured it recently too,
good luck w/ it, yea if the deca dont help have doc look, c-ya,,
