Thank you for your query.
1. Since this happened almost a couple of days ago, the worst is probably over.
2. The direction of the force, speed of the elbow strike and your own and the opponent's body weight and position would have been the factors responsible for your symptoms.
3. The thyroid cartilage
of the voice box usually deflects the force of a thin object above or below. With a large surface area of contact, such as with a bent elbow, it is difficult to predict the outcome.
4. To complete the list of possible causes and not necessarily in your case, there may be a slight damage to the delicate inner ling (mucosa) of the larynx. The cervical spine
may be injured leading to muscle spasm. The esophagus
(food pipe may be crushed between the larynx and cervical spine.
5. The low voice and sore throat
is due to the injury. Get a Videolaryngoscopy (or at least an IDL or InDirect Laryngoscopy) and USG Neck (Ultrasound
) done. If it is normal, there is no cause for worry.
6. If your symptoms worsen, or if you have pain while swallowing or breathlessness, a CT Sacn of the larynx is advised.
7. Permanent damage is unlikely. Stop any contact sports for some time till you recover completely.
8. I must emphasize that the chance of a serious permanent problem at your age is rare. Even is some damage shows up in the USG or Scans, the treatment will be conservative medication and observation. Ask for a prescription of anti-inflammatory pain killers and steroids
if the inflammation is severe (and you do not have a history of diabetes
