Thigh numbness after isometric split squat

Approximately 10 minutes after isometric split squats on the knee pain template Day 5, I noticed the outside of my left thigh felt numb (lateral quadriceps). It was still numb the following day, but over a smaller area. The numbness gradually went away over three days, but came back the following day after the isometrics (today). During Spanish squats today I felt slight tingly on lateral quadriceps near the patella. During left leg split squats it felt like thousands of tiny bugs running around under my skin in the full lateral quadriceps area. It also felt hot. Both these were only during the sets, but gone immediately during rest. However, the numbness returned some time during the workout and still there now as I write this 2.5hrs later. The numbness isn’t as intense as the first time and covers a smaller area. No other symptoms of any kind that I have noticed. I’m not sure how to proceed. Is this just a load management issue? Since it went away before should I just continue or maybe change split squats? Thanks in advance for your help.

Were you wearing a belt when this happened? It’s not uncommon for lifters to occasionally get some numbness in their lateral thigh if their belt is on too tight almost akin to your arm falling asleep if you have pressure on your funny bone. My first recommendation if this is the case is to perform them unbelted next session and see if that changes symptoms.

Thanks for the reply. No I’ve not been wearing a belt at all. Since posting I’ve moved onto phase 2 and I’m still experiencing just the numbness. It has gradually reduced to now cover about 40% of the length of my thigh (down from about 95%), and the numbness has decreased in intensity. I’m unsure if I should still be concerned, since it has now been 16 days since it first started, or if I should be ok since symptoms are reducing.

If it is decreasing I would not worry much about it at this point. Sometimes we catch a nerve and you will have numbness in a sensory area for a little while. So long as it begins slowly resolving this is something that is more than likely harmless.
