The blind masseur was right. However, your symptoms seem to be beyond the normal range of pain. It may be that the amount of stimulation is too large and too heavy. It is recommended not to massage for three days, and pay attention to observe whether there is any further discomfort. In addition, don't be too nervous, the general massage won't cause any big harm. Just rest for a few days. It's good to have an old job, but don't forget to exercise.
