Pain in two upper chest bones. Lockdown.

I'm suffering from pain in my upper chest bones (maybe clavicle).It started from a week ago, but the pain isn't persistent i.e it happens and then goes and comes, last for hours or a day and then again goes.Along with that, I'm suffering from internal tremors or vibration in chest and abdominal area.A fluttering sensation occurs when I try to deep breathe.Recently, I was prescribed for reserve plus(don't know Whether it will get the job done or not) for 10 days.Im on it.Apart from it, I'm suffering from muscle losseness I.e I find myself pulling or pressing the muscles easily through my skin.Sometimes difficulty while breathing while eating or reading or talking, weakness and few a time headache.Doctor, it is a very kind request from me to you that prescribe some medications or tips so that I can take it accordingly in these pathetic lockdown.
