Out of cast after 4 weeks (long arm) muscles in forearm tight n painful n numbness in thumb normal post cast? I had epychondolitis n torn tendon

Out of cast after 4 weeks (long arm) muscles in forearm tight n painful n numbness in thumb normal post cast? I had epychondolitis n torn tendon

Can be expected --: Stiffness from being in a cast for 4 weeks. Numbness maybe from cast being too tight or the cotton padding may have bunched up causing a local neuritis, which should clear up in 2-3 weeks time. As you exercise the tight muscles should loosen up and get stronger, reducing the stiffness as well.
Massage/stretching exercises would help the epicondylitis. The doc should advise re: the torn tendon! ...Read more

Muscle (Definition)

It is a body tissue that has the ability to contract. It shortens and generates force. It relaxes and returns to its original length. Muscles move joints, stabilize the body, move air and food through the organs, act as valves for bladder, bowel and other organs. They control movement of the eyes. They help us express ourselves by changing the shape of our ...Read more

Out of cast after 4wks (long arm) forearm muscles tight n painful n numb thumb. Normal after casting? Have epychondolitis n partial tendon tear

Not normal: Numbness is never normal, a nerve may have been irritated by the cast. Epicondylitis should never require a cast, even with a partial tendon tear. I recommend seeing a sports medicine trained doctor. ...Read more

Muscle fibers forming pacemaker are less striated than other muscle fibers. But does it help the pacemaker conduct impulse faster, how?

Muscle fibers forming pacemaker are less striated than other muscle fibers. But does it help the pacemaker conduct impulse faster, how?

Not clear?: No muscle fibers make the pacemaker. Pacemaker is an artificial device implanted in one's heart. The leas of a pacemaker are not in the muscle but in one of the heart vessels. ...Read more

What are the functions of cardiac muscle fibers?

What are the functions of cardiac muscle fibers?

See below: The heart is a muscle with very special qualities. The main bulk of heart muscle helps pump blood to the lungs to get oxygen and then pumps that oxygen rich blood to the rest of the body. Then there is a special type of cardiac fibers that helps conduct electrical impulses from two "pacemaker" sites in the heart, the sa and av nodes which allow the heart to keep pumping for your entire life. ...Read more

I'm wondering if I eat foods high in protein and fiber can I lose weight and build muscle?

I'm wondering if I eat foods high in protein and fiber can I lose weight and build muscle?

Yes and no: I would recommend you focus on one goal of either losing weight or gaining muscle. It is hard to chase two opposing targets at the same time. For gaining muscle you need to be on calorie surplus and for losing weight you need to be on calorie deficit. Set one goal to lose weight once you achieve it go for the second goal of gaining muscle mass. ...Read more

Had critical illness polymyopathy from status asthmaticus...Now emg normal could I have type 2 muscle fiber damage and that's why normal emg?

How do you FEEL?: The best way to tell how well you have recovered from this complicated illness is by how you feel. Since long-term there's no specific treatment and conditioning is important, you are the one to answer the question. And you're right -- a normal EMG does not rule anything in or out. Hope it's a good recovery, best of luck. ...Read more

Would taking supplements for mitochondria help slow twitch muscle fibers, and what do fast twitch fibers have to be able to work without mitochondria?

For mitochondria?: Please repost your question & include which supplements you mean, how they are supposed to work to "help mitochondria, " why you think your mitochondria need a supplement, and what you expect to achieve with supplements. This sounds as bogus as a $3 bill. You have to be a skeptic about these things. If you're not a skeptic, you'll be a sucker. ...Read more

Does working out increase the size or the amount of muscle fibers? Also, is there a way to increase the actual number of fast twitch muscle fibers?

Does working out increase the size or the amount of muscle fibers? Also, is there a way to increase the actual number of fast twitch muscle fibers?

Muscle strengthening: We are born with fixed amount if muscle. Exercise increases the fiber size, but does. It add more fibers per se. Focused strengthening will reduce fat in muscle and improve the efficiency of contractions. I question if the fiber mix will change but there will significant improvement in performance like, this, so result will be the same. PT or exercise trainers can assist here. ...Read more

I felt things pull from neck and back and now I have a very fibrous feeling in neck and back. Can I be feeling the muscle fibers of torn muscles or li?

Muscle fibers: Muscles fibers are correct they "lock" up when not stretched properly and can cause significant neck pain along with decreased range of motion. Warm compresses and stretching should help. In extreme instances I have done trigger point injections, but very rarely. Hope this helps. Dr d. ...Read more

Does stretching break the muscle fibers the same way as resistance training?

Does stretching break the muscle fibers the same way as resistance training?

No: The effects of muscle stretching are different than resistance training. Both are important. Stretching, particularly after you are warmed up helps balance the muscles from the front of the body with the muscles in the back of the body. This is important to avoid injury and help your joints work with less stress. Resistance training will build muscle strength by inducing muscles to enlarge. ...Read more

Do certain muscles have a greater portion of certain muscle fiber types over other ones? Like do hamstrings contain more type II or type I fibers

Do certain muscles have a greater portion of certain muscle fiber types over other ones? Like do hamstrings contain more type II or type I fibers

Depends on training: Muscles involved in endurance activities typically have more type ii slow twitch fibers, however depending on how one trains, the balance between type I and type ii fibers changes.

Endurance building workouts and training will generate hypertrophy in the slow twitch type ii fibers, while pure strength building workout tends ot build more type I muscle tissue. ...Read more

Achilles tendonitis- stretching pulls muscle fibers away from each other, making healing process longer. Do you agree? Healing advice? How long?

Achilles tendonitis- stretching pulls muscle fibers away from each other, making healing process longer. Do you agree? Healing advice? How long?

Rest and immobilizat: It may take a long time to heal achilles tendonitis because of the poor blood supply to the achilles tendon. Therefore rest, immobilization, shioes with heel lift, such as running shoes, orthoses to relieve stress on the achilles tendon and gentle stretching as well as ice and massage of the tendon are all good treatments. We also use physical therapy from a sports pt. ...Read more
