Serrapeptase is very effective in disolving scar tissue inside the body. You might try it but beware it also dissolves parasitic colonies so you might need Iodine to go with it.
Other than this, you should really try supplementing with magnesium (preferably orotate or at least malate form) and make sure you get enough potassium (the most harmless way to do it is to eat lots of potatoes, I don!t really recommend chocolate but you may try 85% chocolate to see if it makes any immediate difference in your symptoms). Beware there is a delicate balance between potassium and sodium and it can go wrong either way.
