Saline solution symptoms and conditions

I am a 52 year old women , except for a yearly resistant sinus infection I would describe myself as very healthy and have only minor aches and pains for my age. I was prescribed Levaquin by a walk- in physician after 2 months of a sinus infection. Within a week I felt 100 years old . I could barely get out of bed, the pain in all my joints was excruciating the first 5 minutes and didn't improve a lot during the day . I didn't think my legs would hold me upon rising from any position. After one week of finishing the drug I started to feel better.......it has been two weeks now.... I'm still sore and weak , especially noted in hands and legs .

While taking this, I have experienced water on my knee, aching in my leg and then a problem with the right knee, aching in arms and shoulders. All of this could be something else, or at least the fluid on my knee. I had an MRI Saturday and will hear in a few days.
So what is the best med for sinus infection which is why I am on this.
Thanks.

I just spent 3 days in the hospital due to taking simvastatin.
I was having weakness in my legs and arms, to the point that I could not walk up steps. I finally went into emergency when I took an attack that resembled a heart attack, shortness of breath, cold sweat, trembling and
nausea. They flushed my body with saline solution for two days. I now have the use of my legs, but am very weak.

Just went through an arteriogram after failing the EKG part of a thalium stress test. No blockage was found. I had experienced chest pain radiating into my arms upon walking just a half block or up steps, so my internist ordered the stress test.

The nurses and doctor kept asking if my heart rate was always this low (about 40-46 while recovering from the arteriogram), and I said it was usually in the 50's. I had constant headache, frequently with upper right jaw pain (dentist said all was okay there). I took more and more aspirin and ibuprofen to counteract the pain.

My neck was killing me--thought it was from work, but I had never had this much pain and stiffness before. I had increased heart palpitations and extra beats. I am also on Atenolol for tachycardia, and I thought I was fine, until my doctor thought I needed more blood pressure medicine to get the BP below 130/75. I questioned his thinking, but went on and took the lisinopril.

The cardiologist told me to stop it for 5 days to see if I feel better. I have had two days without headache now, and that is a miracle! My heart seems more stable, too. It is too soon for me to go walking, but I bet I won't have the same chest discomfort as I did! I don't think my heart was beating hard enough or fast enough to take oxygen to my muscles when I was exerting myself. This stuff should be taken off the market!
