Hi,
Welcome to health care magic,
I have read your query and understand your concern.
As you have mentioned you have pain in your right arm to chest side which was gradual in onset without any trauma or
injury.
Here, I would like to know that whether you have any history of
diabetes or
thyroid illnesses or any blunt hit to the arm?
There could be either muscle
sprain or pull but needs to be evaluated further if it is troublesome.
The initial treatments for all these are,
1. Avoid repetitive overhead or arm activities
2. Do not carry any heavy object or bag on affected shoulder or arm.
3. Apply ice packs for about 15 minutes twice or thrice daily.
4. If you have learned how to do exercises then continue with that it's could be effective .
5. Apply
diclofenac based topical ointment which is more effective than
paracetamol based.(available over the counter)
6. Also you can take oral pain killers if pain is very severe.
7.Re-nerve Plus,as it is just a
multivitamin supplement which is good for nerves (more useful in diabetic patients).
If still pain is persisting then proper examination of arm with right shoulder joint is required to find the exact cause and if needed x ray and MRI should be done.
You can consult nearby doctor or orthopedician who can write X-ray and MRI of the shoulder after taking complete history and thoroughly clinical examination.
Thanks and Regards,
