Hello, Thank you for contacting me at Ask a Doctor . I will try to answer your question to the best of my ability. This does sound like a simple muscle strain. It may well be that the quadriceps area it is very tight and this has led to a simple pulling of the muscle fibers. Most of these simple muscle strains will get better with simple conservative treatment. Ice will help with pain relief. If you feel stiffness in the area and then heat will help. Take a simple pain medication such as Tylenol. If the symptoms are getting worse over the next few days, then I would suggest seeing your primary care physician. I hope this information is useful for you. Please do not hesitate to message us back if you have any further questions. Best wishes, Adrian Rawlinson MD
