The local fat degeneration may happen if the person who mixed up the shot added lidocaine with epinephrine rather than plain lidocaine! ...Read more
What is the difference in the exercise prescription for building muscular endurance vs muscle strength ?

Endurance would be training for long periods of time usually at a reduced rate. This would be a distance runner. Usually it is best to cross train, or train for both as in doing so you can develop both types of muscle fibers, fast twitch (strength) and slow twitch (endurance). ...Read more

Sometimes sneezing can aggravate pain if there is a small tear of the outer coating of the disc capsule but even so there is an excellent chance of total resolution. Stay active, lift using your legs ( don't bend your back forward) and consider ice packs/OTC NSAID for 3-7 days. ...Read moreSee 1 more doctor answer

Some relation: Muscle mass has to do with hypertrophy of muscle fibers. Muscle fiber hypertrophy has more to do with the consistency of training routine, not single episode of power.
