Is it possible for soreness from an injury to show up weeks after an initial injury during which time you felt no effects?
I work for a major delivery company.
On a rainy day I slipped and fell on a wood deck ramp. This was a 100% fall flat on my bottom. In a split second I knew there was no catching this to help with the impact. My feet went out from under me and it seemed like I was airborne for a moment. At least my center of gravity had gone away from my legs completely and shifted to my bottom. I stopped the motion when I was flat on my back.
I immediately assessed the pain and within seconds got up and walked away. For a few days the spot where I landed felt like a bad bruise. I watched for bruising to appear but nothing aside from a red spot ever developed. I kept active and everythng went away to the point where I forgot about this incident.
During the following month was the Christmas peak season, the busiest time of year. I worked 11 hour days 5-6 days each week for 3 weeks. This fall had no bearing on my activity. I do not remember thinking about the effects of the fall. I was not aware of any lingering effects. A week after Christmas I woke up on a Saturday and my lower back felt like a pulled muscle. I thought about the previous day and recalled moving a package in the back of the truck and feeling a strain. I discounted it as typical of things I go through and that go away on their own all of the time. There was nothing special about it except that I did tie the two together when I was thinking about when I felt anything that could have been the source of this soreness. This soreness was like the way you feel sore muscles a day or two later on after you exercise. After moving the box I was able to continue working that day and did not think about it until the next day.
This pain did not go away like every other strained muscle I had experienced. I went to work on Monday but Tuesday morning I realized this was a consistent injury that was not healing. The pain would lessen as I loosened up and worked but it could get so bad I could not stand up straight and it was uncomfortable sitting or standing in certain positions.
I saw a doctor and it was diagnosed as a strain. I just saw a physical therapist. She asked a lot of questions. She described techniques for movement and explained the logic behind them. My first night lying down after the physical therapy session I used some techniques to carefully move avoiding certain muscles. It was then that I put it all together and realized that the worst pain is where I hit the deck.
This strained muscle has felt like a bruise all along. I never thought of the fall it had been weeks earlier. I had recovered from that and been very active moving, lifting, walking, climbing for long hours without impairment. The doctor had an explanation that fit with a strain although he and the physical therapist asked about falls. I did not even think of the earlier fall until the physical therapist had explained how muscles behave when making movements. Now I think this could even be a slight bone fracture.
I will be talking to the PT and doctor about it but I am just doing some preliminary research.
