Hi.
First of all, please do calm down. I understand that you are very anxious about your symptoms but this may further aggravate them if you do not try and control your anxiety.
Your symptoms are, at the moment, non-specific and cannot suggest any particular disorder that would be the certain cause of your condition. Although amyotrophic lateral sclerosis can present with some of your symptoms, it would be premature to consider it as a primary diagnosis without any ancillary tests done such as an electromyography (EMG). Furthermore, ALS usually presents with muscle atrophy and weakness, and spares cognitive and sensory functions.
Some conditions that could possibly cause your symptoms include nerve or spinal cord compression secondary to degenerative disk disease or disk herniation, vitamin and mineral deficiencies, endocrine disorders, osteoarthritis, etc. However, the presence of backache and predominantly one-sided (in this case, the right side) symptoms might suggest a spine disorder leading to nerve or spinal cord involvement as more likely of the aforementioned conditions.
I would advise you to consult a neurologist to have a complete neurological evaluation done and to, possibly, schedule you for an MRI to determine the underlying cause of your symptoms.
Hope this helps.
Good luck.
please tell me your opinion. I'm waiting for that unpaciently.
