I have never ever, in the hundreds of shots that I've done, experienced something like this. This is the absolute strangest thing I've ever heard of or seen, and never seen it posted on here. I always rotate shots, between my quads, and my glutes. So everything gets about a week and a half before its stuck again. Well I stuck my left quad with 1ml of test on Sunday. A few minutes ago as I was getting up and rubbing my legs, I heard this weird, kinda, ...I dunno....liquidy sound. So I kept running my hand down my left quad, and I kept hearing the sound. It sounded kinda squishy, or like the sound of someone ringing out a sponge. So I put my hand on my left quad, applied some pressure and just pushed rapidly a few times, kinda tapped on it. And it make that repeated sound. I've never heard about this before. Ever. In the whole time I've been in the gear scene I've never even heard of this. My other quad doesnt do this. Now here's the deal. It doesnt hurt, no redness, nothing swollen. No signs at all of an infection or anything like that. It just makes the sound. I'm not above going to the doctor at all. Thats what I hate to see here the most, guys having major problems and then refusing to see a doctor about it. If I'm having a problem, I'm going to see someone and thats that. However this time I'm not so sure. Insurance isnt so great right now so it would cost me, and I'm kinda tight with funds this time of year. It doesnt appear there is anything wrong at all. Just the sound. Any help from anyone?
