Almost There

Well I need to keep logging these feelings or they will forever be lost. First I have yet to have any really serious episodes of any kind these past couple of weeks, which I am extremely grateful for.
As of December, my beta-blocker dosage was cut and half and has since caused about twice the chest pain I was previously experiencing. I was told it would help with the fatigue, hair loss and need for tons of sleep, but thus far I don't know that much of these things has changed. I have been trying to up my exercise efforts.
I have started walking about 3 miles a day. I don't tend to have any chest pain as a result, but I don't really know that it is helping my cardiovascular fitness either. Running and lifting are a slightly different story. It is actually the running that is really hard. I can push through pain I just think its a bad kind of pain to push through. I think it is the result of the duration I spend at an elevated heart rate. On Monday I ran for 3 miles and I was feeling the aftermath all night long. A lot of burning in my chest and pain. The chest pain had kicked in from the onset of my warm-up and all the way throught the run. The following day my legs and rest of my body really felt like they had been hit by a baseball bat. I need to see if this has any correlation with a potential lack of blood flow to these muscles.
Otherwise all is well. I am getting much closer to my 1 year mark. This will be a celebrated day for years to come:)
