Hi there!
Well, without a clinical evaluation it would be difficult to determine the cause of your symptoms. Possibilities that may need to be considered include infections, inflammations, degeneration, nutrient deficiencies, hormonal/ endocrine/ metabolic issues, neuro-muscular causes, drug/ medication side effects, allergies, autoimmunity etc. More than a single cause to the symptoms is a high possibility. At this stage it would be best to have these evaluated by a primary care physician initially and depending on the cause(s) diagnosed or suspected, it can be managed accordingly or specialist care may be sought.
Hope this is helpful.
Take care!
