Welcome to HCM.
Based on the information provided, the bulkiness on your shoulder you have been experiencing could be due to increased and irregular fat deposition ( lipodystrophy
which is common among women) in those areas. You have not mentioned anything about your weight. In case if you have gained a lot of weight in these 2 years, then the bulkiness can be attributed to that.
The stabbing sensation could be due to Cervical spondylitis
. You need yo get an X-ray of your cervical spine
done to rule out spondylitis. Physiotherapy
and medication shall relieve the pain
causes lipodystrophy so please get your Thyroid profile done and get treated accordingly. You have not mentioned anything about your age and comorbid conditions like diabetes, obesity or thyroid issues if any.
Using muscle relaxants like Chlozoxazone in combination with diclofenac should help you in relieving the pain.
Dont worry. I dont think you need any surgery. Physical exercise will help in burning the excess fat. In case if you have been diagnosed with thyroid problem, then get treated accordingly.
Hope you got the solution you have been looking for.
