I know this is a long post, but I would be very thankful if you could help me.
When I was 17 years old, I did some very heavy deadlifting and squatting with too few rest days inbetween and one day I woke up with an extremely sore back and pelvis-area unable to walk because of the pain. The pain cooled down during a few months but over the years since then my back has only gotten worse and worse.
The problem often starts around the lower back and then spreads to my bottocks and the rest of my back. Sometimes it continues from the pelvis area down the leg. It feels like something inside is blocking me from doing movements.
I have chosen to write some examples of situations that happened to my back over those years, so that hopefully someone with experience or knowledge will be able to recognize my issues:
1: When i was 18-19 years old I had to get to somewhere really fast, so I ran as fast as I could. The more I ran, the more my back started to hurt. At the end of it, I had to stop and could barely stand up. However, all the pain disappeared not long after. So unlike with the deadlifts, I didn´t get sore muscles.Rather, it was like something was blocking me from using all my power.Happened a few months later again.
2: As a 22 year old I had a physical fight with my brother(, not a serious one). He is much younger than me so I did not have to use much power, nor did I get very tired. Yet, my back started to hurt more and more and in the end I tried to kick him, but my back gave in and I fell to the ground and couldn´t get up. And unlike the last example, this time the pain stayed there for days.
3: I have since tried to get back to the gym several times , but every time I do weighted squats or deadlifts, the back spasms will come some hours or days later. In spite of being able to squat 60 kgs (about 130 lbs) for several reps and sets, my back will be hurt from just lifting 15 kgs.If I stop early, the pain doesn´t get that bad.
There are also positives:
4: One itme, I managed to get all the pain away simply by standing up, bending over and touching my toes. When I straightened my back afterwards, the pain disappeared completely.It came back the next day when I was doing some kind of physical activity though.
5: Another time, all of the pain went away by me using a massage ball on my bottocks. Not just the pain in the pelvis area but the rest of the back too. This doesn´t work when the pain is at its worst thougjh.I have also tried a regular thai massage. After the massage, all of the pain went away but slowly came back during the next hours.
What confuses me about the problem is that:A: I can easily lift decent amounts of weight with my back. Similarly, I could easily fight with my brother without having to use much of my strength and without getting very tired. Yet, even though I am not pushing myself that far, the back spasms still come and I have to either use a massage ball or lie down for several days.B: Doctors and physiotherapists have found absolutely NOTHING wrong with my back or my pelvis area. Some had said that some of my upper back muscles are not as strong as the rest of my body, but no one has been able to explain why it gives me those back spasms. Another said my muscles were very tight, but also wasn´t sure what the problem was. Another one has said that it sounds like some kind of strain in the back from overtraining, but he too does not have a definitive answer.C: I find it weird that a massage ball on the buttocks, a regular massage or touching my toes can actually make a lot of the pain go away. This indicates to me that 1: something inside my back or pelvis area is somehow "stuck" for a lack of better words. 2: That a lot of the pain starts from the pelvis area, since massaging my buttocks is enough to make the rest of my back relax. 3: That a since a reagular massage can make a lot of the problems go away, that indicates that some of the pain also residing simply from tension in the back.
While these indications do give me some idea of what is wrong, they do not draw the full picture. Therefore, I want to know if any of you know about this. Have you experienced or have professional knowledge of something similar? Could it be a weak pelvis? Other weak muscles? A stuck nerve? Strong tension? A psychological problem? If you know anything, please let me know.
