Last night I was reading about Lymph system and that the generator for lymphs is in lower back, bottom of spine.. It often is blocked and the root physical cause of a system malfunction. It according to article packs lymph with toxins as a last resort, when the rest of system has failed to keep up. This to me indicates your root issue may yet still be discovered, that Lymphoma may be the end result of a deeper PH issue that MMS attends to nicely.
That said I will give you Osteopath and sacral cranial as two search terms that you may find helpful to your condition. Do not get an Osteopath who wants to prescribe drugs, you want one that can read your body and do the manipulations to reset the blocked channels.
It also might be called Tailbone Manipulation.
Of interest to me in what I was reading was the discussion about the skull bones moving. Western believes they do not, alternative believes they do.
I believe they do, not because of anything I read but due to my own experience and because Osteopath believes the bones move and are integral to healing, I offer you the info I have for your condition, as I understand it, hopefully for your or someone`s benefit.
As to buying MMS. There is a list of Jim approved sellers and a ton of non approved sellers online.
I have not heard of anyone being `scammed`so I think whatever source you choose will likely be good. Type buy MMS and your area into Google see what ya get.
I believe you are very wise to MMS a few weeks, doing the protocol seriously and see what things look like in a month.
Whatever you decide, all the best
