Other than medication, what can I do for pain relief from masseter tendonitis?

It is more effective to inject the 20 units in the lower and more posterior parts of the muscle as the aim is to achieve a V shaped lower face, therefore the lower and posterior parts of the muscle should be targeted to shrink more. By placing 20 units in one spot only, the doctor can not reach the other parts of the muscle and you may just get a overall sunken face rather than a slim tapering lower face. Also , by injecting in the lower and posterior parts , the doctor can avoid Botox fromflowing in front to the risorius muscle , which will cause an asymmetrical smile .

Hi, you should definitely see a doctor/go to A&E immediately as a matter of urgency, as your chest pain has lasted for weeks and has shown signs of worsening. Chest pain is one of those symptoms that you should NOT ignore. While it’s indeed often due to "less-worrying" causes, it's better to be safe than sorry. Even minor chest pains can sometimes be a sign of coronary artery disease and clogged heart vessels - up to 30% of heart attacks have barely noticeable warning signs or symptoms.
