Hi,
Sorry to hear what you are going through. The symptoms you describe could be caused by:
* peripheral neuropathy
* Neurologic disorders like MS
* ionic imbalance (like low calcium, low 
magnesium)
* 
vitamin deficiency  Nerve destruction/
injury during a surgical procedure may give such a presentation. However, 
abscess drained in colon may not necessarily be the cause.
I will suggest you try the following:
- Eat well and health with enough vegetables
- Take B complex vitamins
- Your doctor may also prescribe a nucleotide based drug like Nucleo
- CMP forte if need be.
See you doctor for tests like serum electrolytes, full blood count, electromyogram, liver and 
kidney function tests and if need be, a brain scan.
Hope this will help. 
Best regards,
Dr. Mbuomboh Veranso
