I used to be a weight lifter before falling ill with fibromyalgia. I was at a point of sculpted back thigh muscles, two hour a day workout with two hours of additional cardio. When the doctors can't find anything, it is possible the pain is from fibromyalgia, arthritis or another nervous system or muscle condition. Not everything shows up in bloodwork or imaging tests. A Rheumatologist needs to diagnose it. However, you're young, it's rare to have something like fibro so young. I personally went from strong, the top of my game, to barely being able to lift a heavy glass, or open a door. Mine started in the joints, specifically the hip and shoulder joints I tried cortisone, but that only gave temporary relief. When I fell ill, I wish I had done some checking before starting medication. So I'm going to give you some advice on things to try and things for the doctors to check before going down the path of considering medicine for a fibromyalgia-like disease. With any luck, starting these supplements will help you get back to normal in one to two months time. Be patient, the body takes time to rebuild. You also have the added challenge that your body is growing until the age of 25. So, you need even more food and supplements, like double the need.
I think as a start, you need to focus on what supplements you're taking. Animal Flex, and Super Cissus have helped others, but I don't think it is enough in your case. It is a good start, though. These ones only cover a small group of supplements/vitamins needed to support a body with a weight lifting routine. Because your muscles hurt even after something straightforward like push-ups, it means they are not getting enough nutrients to recover. It's important to get enough protein in your diet, either through meat or taking something like whey supplements. Pain can be caused by a lack of amino acids provided by the protein, lack of magnesium, a lack of Vitamin D or an electrolyte imbalance. Basically, you need to feed your muscles either through food or through supplements. Once you get on a vitamin routine, you will start to see times when your muscles are ok, but it will take a month or two before you see consistent results. I would recommend asking the doctor to check for certain levels in your blood for Vitamin D, B12, Iron and Thyroid. My guess is the doctors have already checked for the basic stuff because they went as far as checking your inflammation factor, but some neglect to check Vitamin D and B12.
To see if you have symptoms pointing to a vitamin deficiency, I've included a site of symptoms to vitamins. If you're having muscle twitches, like in the back or eyelid, they you're definitely deficient in magnesium, which will result in incredible pain after even small workouts.
Also, it's important to take the right balance of supplements. Animal Flex has zinc, and too much zinc will likely interfere with the metabolism and absorption of other essential minerals in your body, most especially iron, magnesium and copper. So taking extra zinc without balancing it with a multivitamin could cause you pain. That's the challenge with some bodybuilding supplement companies, they lack the science behind keeping supplements in the right ratio (plus it costs more, and the quality is suspect).
It's also important to take it easy with workouts until your muscles recover. Exercises through the pain will only tear your muscles resulting in a more difficult recover road. Doing light stretches, walks while building up your body chemistry will help. Drinking lots of water will help flush any toxins and build-up out of your muscles, make sure you drink at least 8 glasses a day, more if you live somewhere warmer. Also make sure you take your vitamins with a protein for them to be better absorbed by your body.
I'd like to hear back to help you while you rebuild your health. If supplements don't work, I have other suggestions to look for. I order my supplements from iherb.com, it's much cheaper than my local stores. DEX579 coupon will get you $5 off your first order, plus you can pick out something for free with each order.
