Thankyou for replying. I shall arrange an appointment with my Doctor to get it checked.
Hi there!
Well, without a clinical evaluation it would be difficult to tell. Likely possibilities that may need to be considered include muscle strain, excessive workout with lactic acid accumulation, inflammations/ degenerations such as tendinitis/ tendinosis, dislocations, fractures, nerve compression, myopathies/ neuropathies, trauma/ injuries, vascular/ mineralization issues, metabolic/ endocrine causes etc. It would be best to get this evaluated by a primary care physician or an orthopedician for an accurate diagnosis and appropriate management.
Hope this is helpful.
Take care!
